The UHFLI (ultrahigh frequency lock-in amplifier) demodulates signals of up to 600 MHz using fully digital signal processing, while providing 100 dB dynamic reserve over the entire frequency range.

Washington, DC--NASA awarded $3 million to Space System/Loral to host a space laser communications relay demonstration terminal payload aboard a Loral commercial satellite.

A 2D pitch-reducing optical fiber array (PROFA) bridges from/to singlemode or multimode optical fibers and  dense PIC-based VCSELs, receivers, or vertically coupled gratings.

San Jose, CA--NeoPhotonics Corporation received a $39.8 million dollar investment from RUSNANO and plans to use a portion of the proceeds to establish design and production capabilities in Russia by mid 2014.

Long-wavelength pumped, periodically poled lithium niobate waveguides upconvert single photons, allowing efficient, low-noise silicon avalanche photodiodes to detect the signal.

Washington, DC--Next year's Conference on Lasers and Electro-Optics (CLEO), held annually in San Jose, CA, will take place in June rather than its usual May, moving to June 9–14, 2013.

East Granby, CT--Nufern has been awarded multiple contracts on competitively-bid programs to build a total of 46 compact, >1 KW fiber amplifiers in support of multiple government laser efforts.

Fiber couplers that operate at 2 µm are built on singlemode fiber and come in 2 × 2, tap, and cascaded configurations.

The demand for better connections between Tokyo and London is driving construction of the first submarine fiber-optic cables to span the Arctic Ocean.

Washington, DC--BioPhotonic Solutions is the winner of this year's CLEO/Laser Focus World Innovation Award.

Education and fashion are two sometimes related topics of interest to the general public and—as we show in this issue—the photonics community.

A technique to deposit precisely doped semiconductor materials into microstructured optical fibers (MOFs) is coming of age, demonstrated by gigahertz-bandwidth photodetectors built directly into a fiber.

Singapore--A group at the A*STAR Data Storage Institute has fabricated electrically pumped III-V semiconductor lasers and novel cavity mirrors on top of silicon chips -- a step forward for optical data interconnects

Meeting the needs of 100 Gbit/s transmission systems, the XTM-50 and XTA-50 flat-top optical tunable filters feature an ultrafine option to reduce minimum bandwidth to 4 GHz at 1550 nm.
