Thöny comments, “With LayTec’s state-of-the-art in- situ metrology we are able to meet the growing demands on precise process control and optimisation, which is the key to high yields and low costs.”
«For LayTec, an OEM cooperation with Evatec is of strategic importance,” adds LayTec‘s CEO Thomas Zettler. “It will enable implementation of our metrology into processes beyond LayTec’s established applications. And when Swiss precision meets German quality standards, the expectations can never be too high.”
LayTec develops and manufactures integrated in-situ and in-line metrology for thin-film deposition and other high value generating processes. Currently, the company has more than 1500 metrology systems installed worldwide and offers a global customer support and service network including local representations.
u²t unveils 1550nm photodector
The III-V based detector supports systems for next generation networks using 400 Gbit/s or 1 Tbit/s coherent detection-based optical transmission
u²t Photonics AG, a provider of optoelectronic components, says it has developed the world’s fastest balanced photodetector offering a 3dB bandwidth of 70 GHz.
The BPDV3120R complements u²t‘s product portfolio of ultra high speed photodetectors and receivers.
The optical frontend consisting of a monolithic balanced photodetector chip with on-chip biasing has been successfully tested in a system environment and will be used in Test & Measurement (T&M) equipment, such as optical modulation analysers, for the test of next generation coherent network components and modules.
The coaxial single-ended output can detect up to 64 GBaud polarisation diversity x-QAM signals featuring highly reliable results for common mode rejection ratio, linearity and optical input power.
This means the device can be used in next generation long haul transmission systems at data rates of 400 Gbit/s and beyond. At the same time, the BPDV3120R is well suited for T&M applications as well as ongoing R&D activities at high Baud rates.
“While 100G coherent systems are being widely deployed today, we can already see that 400 Gbit/s or even 1 Tbit/s systems will be required in a few years to support the continued exponential growth of data traffic in mobile and fixed networks,” says u²t Photonics CEO Andreas Umbach. “Our 70 GHz balanced photodetector provides one of the key building blocks that will enable systems providers to build and deploy systems operating at 400G per wavelength or higher.”
u²t started sampling the BPDV3120R in March 2013 and will start its production in June.
u²t Photonics AG is a privately-held company headquartered in Berlin, Germany. It offers a comprehensive and fully TELCORDIA qualified portfolio.
Veeco receives NASDAQ notice about late10-Q filing
The MOCVD system manufacturer did not file its quarterly report on Form 10-Q for the quarter ended March 31st 2013 in time with the SEC
Veeco Instruments received a letter from the NASDAQ Stock Market LLC on May 13th, 2013 that it is not in compliance with NASDAQ Listing Rule 5250 (c).
As previously announced, this Form 10-Q, as well as the company’s annual report on Form 10-K for the year ended December 31st, 2012 and quarterly report on Form 10-Q for the quarter ended September 30th, 2012, were not filed in time.
This was because Veeco was reviewing the timing of the recognition of revenue and related expenses on the sale of certain of its products. The accounting review was announced on November 15th, 2012.
The company intends to file its Forms 10-Q and 10-K as soon as reasonably practicable after these accounting matters have been resolved.
Veeco had previously announced that it had submitted to BPDV3120R 174
