Plasmonic Metafibers Simplify Electro-Optic Modulator Integration
ZHEJIANG, China, Aug. 30, 2023 — Electro-optic modulators (EOMs) are critical elements in the optical communication networks that control the amplitude, phase, and polarization of a light via external electric signals. Aiming to realize ultracompact and high-performance EOMs, most...
Open Platform Supports Laser Integration on Silicon PICs
MOUNTAIN VIEW, Calif., June 7, 2022 — Newly launched company OpenLight has introduced the first open silicon photonics platform with integrated lasers. The platform reaches a level of laser integration and scalability that enables accelerated development of high-performance photonic...
Modulator Expands 3D-Imaging Possibilities Using Standard Cameras
STANFORD, Calif., March 30, 2022 — A team at Stanford University has developed a device that that enables lidar functionality with ordinary CMOS image sensors. The device makes it possible to obtain 3D data from technology that, on its own, is capable of seeing only in two...
Integrated Device Modulates Light Without Dimming It
NEW YORK, Nov. 29, 2021 — Researchers at Columbia University School of Engineering and Applied Science have developed a device that modulates visible light without dimming it, and in a small footprint with low power consumption. The work holds implications for applications...
Understanding Actively Q-Switched Solid-State Lasers
Sep 4, 2014 — With an increased quantitative understanding of the operation of Q-switched lasers come huge benefits for laser design. This first article in a two-part series focuses on actively Q-switched lasers; the second part, in a later issue, will cover...
Fast Phase Modulator Is World's Most Compact
KARLSRUHE, Germany, Feb. 24, 2014 — Using electro-optical signals rather than traditional electrical signals could make the exchange of digital information more efficient.
New Devices Could Realize Optical Microprocessing
WASHINGTON, Feb. 20, 2014 — The future of computing may lie in photonic devices, specifically microprocessors that use light rather than electric signals.
Nanolasers grown on silicon surface
BERKELEY, Calif. – Nanolasers now can be grown directly onto a silicon surface, an achievement that could lead to a new class of faster, more efficient microprocessors, as well as to powerful biochemical sensors that use optoelectronic chips. The results are...
GigOptix, Civcom Receive BIRD Grant
PALO ALTO, Calif., Jan. 20, 2011 — High performance electronic and electro-optic components supplier GigOptix Inc. and Civcom Devices and Systems Ltd. announced that they have received a US-Israel Bi-national Industrial Research & Development (BIRD) Foundation grant to develop...
Fujitsu Cuts Optical Switch Power Consumption in Half
KAWASAKI, Japan, Nov. 10, 2010 — Fujitsu Laboratories Ltd. announced its new optical waveguide switch consumes only half the power of a traditional switch through the use of fine-patterned silicon germanium instead of traditional silicon in the refractive-index modulator. Just as...
Physicists Win MacArthur Grants
ITHACA, N.Y., & CAMBRIDGE, Mass., Sept. 28, 2010 — An optical physicist at Cornell University working to develop silicon-based devices that harness the information-processing capabilities of light and an MIT physicist whose research links the worlds of quantum mechanics and astronomy were named...
Boston Micro Develops Retroreflector for Army
CAMBRIDGE, Mass., March 29, 2010 — Boston Micromachines Corp., a provider of MEMS-based optical products for wavefront control systems, announced it has developed a modulating retroreflector (MRR) for asymmetric fr...
Evotec, Active Biotech Ink Screening Pact
HAMBURG, Germany, March 22, 2010 – Evotec AG announced it has entered into a collaboration with Active Biotech AB to identify small-molecule modulators of a priority biological target, selected by the latter company...
Si Photonics Breakthrough at Kotura
MONTEREY PARK, Calif., Feb. 2, 2010 – Kotura Inc., a silicon photonics product provider, has announced its demonstration of a modulator with two-volt, peak-to-peak driving voltage. Permitting the use of inexpensive ...
IME on Silicon Photonics Research and MPW Prototyping
Jul 27, 2009 — The Institute of Microelectronics (IME), Singapore, has done some research work on silicon photonics research and MPW prototyping. IME will include components (germanium-on-silicon avalanche photodetectors, silicon modulators and...
Helios Project Awarded $12M
GRENOBLE, France, Sept. 4, 2008 -- Helios, a four-year project that seeks to find an innovative way to combine a photonic layer with a CMOS circuit, has been awarded an €8.5 million ($12 million) grant from the European Commission. Helios (photonics electronics functional...
Si Nanophotonics Advanced
YORKTOWN HEIGHTS, N.Y., Dec. 6, 2007 -- Silicon research announced today uses light instead of copper wires to transmit information through the "brains" on a chip. The development could potentially lead to supercomputers -- which today are power-hungry, huge, and run hot -- that fit into...
World's Smallest Silicon Modulator Created
Feb 1, 2006 — AUSTIN, Texas, Feb. 1, 2006 -- An electrical engineer at The University of Texas at Austin has made a laser light blink while it passes through a miniaturized silicon chip, a major step toward developing commercially viable optical interconnects for...
