Second-order nonlinearity paves way to new silicon photonics devices

December 17, 2011

A consortium of researchers in Italy has observed second harmonic generation in a silicon waveguide – the first time this effect has been seen in a silicon waveguide, they say. This is an important step towards making integrated silicon devices in the mid- and far-infrared region of the spectrum, as well as extremely fast optical modulators and switches.

EpiPhotonics touts PLZT waveguide for scalable high-speed optical switches

December 17, 2011

EpiPhotonics has announced development of new low-loss electro-optic (Pb,LA)(ZrTi)O3 (PLZT) waveguides for nanosecond-speed optical switching.

Southern Photonics launches optical modulation analyzer based on equivalent-time oscilloscopes

December 17, 2011

Southern Photonics of New Zealand now offers a new alternative to current optical modulation analysis techniques. The company says its IQScope, when paired with equivalent-time sampling oscilloscopes, can perform optical complex modulation analysis over a wide range of modulation formats at data rates as high as 800 Gbps.

Optical fiber microresonators show promise as optical memory

December 17, 2011

Researchers at OFS Technologies Somerset, NJ, say they have developed a precise and efficient way to construct microresonators by making nanoscale changes to the diameter of standard optical fiber. The researchers say this is “an essential step toward designing a practical optical computer.”

Now the researchers say they have designed a new kind of optical memory that could be commercially available in the next few years. "We can faithfully reproduce these resonators. There’s a real, robust way of fabricating these, and this is the first paper that actually shows that," said Misha Sumetsky, a researcher at OFS Laboratories and lead author on the study.

OE Solutions, AimValley partner for optical transceiver development

December 17, 2011

Transceiver vendor OE Solutions and Dutch technology services company AimValley say they have joined forces to develop optical transceivers for wireless and wireline applications. One goal of the partnership is to integrate Layer 1 and Layer 2 functionality into the transceiver modules.
