ITC to hear complaint about LED / LD patent infringements News & Analysis 3/20/2008 Post a comment The U.S. International Trade Commission has agreed to hear a case filed by a former Columbia University professor with a 50-year engineering career, Gertrude Neumark Rothschild, who has accused 34 companies including Nokia, Sony, Motorola, and Samsung of infringing her patents for LEDs and laser diodes.
Cheap photonic devices production in sight News & Analysis 3/19/2008 Post a comment Researchers at AMO GmbH and the Institute of Semiconductor Electronics at RWTH Aachen (both Aachen, Germany) have developed a cheap method to produce resonant photonic devices on silicon-on-insulator substrate.
OLED lighting technology achieves new levels of efficiency Product News 3/17/2008 Post a comment OSRAM has achieved record values of efficiency and lifetime while maintaining the brightness of warm white organic light emitting diodes (OLEDs). For the first time, laboratory researchers have demonstrated it is possible to improve two crucial OLED characteristics simultaneously: efficiency and lifetime.
Retina implant receives signals, energy wirelessly News & Analysis 3/12/2008 Post a comment Scientists of the Aachen university clinic and the Fraunhofer Institute for Microelectronic Circuits have developed a retina implant that that wirelessly receives optical signals from the outside. The development aims at a technology to restore eyesight for blind persons.

Zinwave raises $10 million in Round B News & Analysis 3/6/2008 Post a comment Zinwave, a start-up focusing on wideband active distributed systems based on multi-mode or single mode fibre-optic cables and targeted at extending in-building cellular and wireless access, has raised $10 million in a B-round funding.
Plugging the laser gap News & Analysis 3/3/2008 Post a comment Researchers at Binghamton University claim to have devised a strategy to bridge the lasing gap with new materials and architectures that could enable applications not now possible.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
