Atmel introduces the new laser diode driver
Atmel introduces the driver of the laser diode (LaserDiodeDriver) —-ATR0885, are used mainly for amalgamating HD-DVD/Blu-ray, DVD, CD player and PC read only memory (CD-ROM) Driver. Since new ATR0885 capsulated and put out with the minima, especially suitable for half a high driver in applied small-scale SLIM driver and disc-shape computer of the desk and DVD player on the notebook computer.
ATR0885 includes 3 output units, any can connect the blue laser diode (HD-DVD/Blu-ray) with wavelength of 405 nanometers , DVD laser diode with wavelength of 780 nanometers or CD laser diode with 650 nanometers. Its product of competition only has output device preserved for blue laser function, but designer’s free choice in 3 kinds of output devices of the system, in order to apply to the blue laser function that ATR0885 can let. This means the designer can choose the optimal output device in the concrete design, thus shorten the lunk as much as possible and make the products designed have cost-effective smaller and even more, offer high performance at the same time.
Up until now, HD-DVD/Blu-ray/DVD/CD system with cost-effective needs 4 apparatuses: The chip of three Shakers and an impedance amplifier each other, and ATR0885 makes it become possible to set up the blue laser system that has cost efficiency very much on condition that only use a integrated circuit.
The blue laser diode used in HD-DVD and Blu-ray system needs a voltage source, this kind of electric energy needs to be able to be dealt with and is higher than frequent voltage of 5 volts used for laser diode of DVD and CD. In order to meet this kind of need, ATR08853 any in one kind of output devices has a single voltage source stitch to offer the voltage up to 8 volts.
In terms of automatic power control, the impedance amplifier is Integrated each other, and support all 3 OCH outgoing channels. The gain to noise temperature ratio of any passway can utilize the single independent resistor to set up separately.
The integral Shaker has reduced the laser mode and jumped(lasermodehopping) . Use a resistor for external use, it can be that all output devices are presumed on the frequency domain of 200-500MHz. Other three resistors allow the excursion of each output unit to be 100 milliamps (peak to peak) . The Shaker can presume under the spread spectrum mode, in order to reduce electromagnetic disturbance at will.
The sample of ATR0885 is capsulated and supplied with small QFN24 of the unleaded, green now. Trigger price is every the unit price of 10, 000 batch is 2.60 dollars.
Blue purple light laser diode of batch productino of Sharp Meet blue light sum HD DVD
Have claimed to already begin to produce the blue purple light laser diode in batches, has become and continued Nichia (inferior chemistry of day) in Sharp The second supplier later, the problem in short supply of part that blue light sum HDDVD apparatus faced was expected to be relieved too.
According to the mandate agreement of crossing with Sony, Nichia began to produce 405nm blue purple light laser diode last spring, and only disclose the factory offering this kind of part, productivity every month hundreds of thousands. Sony produces certain this part too, but all leave and support blue photic PS3, the spokesman of Sony shows too their primary task is to satisfy PS3.
Blue laser part in short supply, blue light sum HDDVD apparatus has been limited, a lot of products can’t be released in time, even it is unable to guarantee the supplying amount to put out, so the appearance of Sharp is undoubtedly a good news.
Sharp spokesman claims, the preliminary productivity of its blue purple light laser diode is 150,000 for every month, and will plan to expand the production line according to the order quantity, has already offered to a customer not famous at present. Xia Pu emphasizes, they have not infringed the patents of Sony and Nichia, but have no intention of disclosing its technological detail too.
The wavelength 406mm of laser diode of Prussian blue purple light in summer, the maximum fan-out capability 20mW in read-only application such as the blue light player, HDDVD player, 5mW exports and makes life-span for 10,000 hours continuously, power consumption 168mW, the price of 10,000 Japanese yen of the sample (84.9 dollars) .
Paying attention to the wave exchanges the work to finish with the assets of Oclaro formally
The news on July 7, Oclaro had claimed to already finish and pay attention to the wave (Newport) yesterday Assets exchange work. According to agreement that reach before, cut wave with the intersection of spectrum and physical heavy-duty the intersection of laser and the intersection of dipole and the intersection of person who run affairs department and advanced photoelectric solution portion to exchange Oclaro of Company ” New Focus” Business. Oclaro has received and paid attention to the extra subsidy of 3 million dollars of wave, the amount spent on relevant trade and integration.
After the trade is finished, Oclaro thinks it will become the maximum supplier on the market of heavy-duty laser diode. It is in metro (the mere network of metropolitan area) that this company shows, this transaction lets Obtain one of the best positions on the market, before this, Bookham and Avanex, two companies, business is amalgamated, for this reason has laid the foundation.
The ones that pay attention to heavy-duty laser diode business and Oclaro of the wave ” New Focus” The business is about equal in scale. From March of 08 to March of 09, the incomes of two companies are 20 million dollars and 30 million dollars respectively. ” New Focus” The business includes photoelectricity, high-resolution driver, optical machinery, tunable laser, vacuum, products of clean room, OEM business,etc..
Tucson factory which pays attention to the wave will amalgamate to Zurich of Switzerland of Oclaro and British Cash Will factory. This agreement also includes the four - year long supply agreement, Oclaro is the only supplier of the physical laser diode of the spectrum in the first year, turn into and supply most products the next three years.

Modulight gains industry's new developing company's award of Frost Sullivan laser diode of 2008
Modulight U.S.A. and the intersection of Finland and two places very glad to announce they growth in earnings win 2008 with remarkable product development strategy and opening outstanding their today branch company have Industry’s new developing company’s award of Frost & Sullivan laser diode.
Predict according to the industry manager Raman Monga of Frost & Sullivan, ” The foundation of Modulight technical development is to the market trend and sharp insight of customer’s demand. They maintain for customer and increase new ability of customer, in addition, the intersection of they and the intersection of customer service and initiative praised to worth bring high growth in earnings.
” We are very honoured to be awarded the reward by top market survey and advisory company such as Frost & Sullivan more primarily. This clear one indicates the efforts of Modulight have gained approval and appreciation of customer and market expert. This has verified is successful that inner strategy is carried out in the past six years. At here, we should express gratitude to our customer and what we set up together for being fruitful, long-term partnership relation. We want to admit too it is the competition that is continued advancing and adding into it by us, efforts which customer make in order to realize the goal of trade growth together that we should express gratitude to us. ” The President & CEO Petteri Uusimaa of Modulight Company says in this way.
The Digital Versatile Disc Player manufacturer sells the essential component of the low-price blue light CD player
The announcer shows, I-TEC is considering introducing the next sincere product of BD CD player ” HD-Media Player” . Product this can gather, keep and broadcast video or video that camera shoots that PC download ’ Fig. 2) .
However, whether exhibit the enterprises or minority of BD CD player on the Hong Kong electronic exhibition. Besides MIT Technology, only Shenzhen promises and speeds(AMTC) And (Samwin Hong Kong) of the Hong Kong dragon Wait for several families.
While inquiring the reason to many Digital Versatile Disc Players manufacturers, these enterprises show, ” Except Japan and U.S.A., other markets have not taken shape. For example, in China, the media price of BD is too high, BD is unsuitable to contain and infringe the environment that the content of information circulates without restraint. After waiting until the stock quantity of PlayStation 3 further increases, it is comparatively appropriate to and then consider setting foot in market of BD CD player ” .
