Achieving The Vision Of Silicon Photonics Processing
By Sandy Wen - 20 Oct, 2016 - Comments: 0

With the increasing need for faster data transfer rates, the transition from electrical to optical signaling in data processing is inevitable. Copper cabling cannot keep up with the upcoming data center bandwidth requirements for applications such as multimedia streaming and high performance computing. One technology that could enable true optical communication is silicon photonics. Silicon is ... » read more

Focus Shifts To Architectures
By Ed Sperling - 08 Sep, 2016 - Comments: 1

Chipmakers increasingly are relying on architectural and micro-architectural changes as the best hope for improving power and performance across a spectrum of markets, process nodes and price points. While discussion about the death of [getkc id="74" comment="Moore's Law"] predates the 1-micron process node, there is no question that it is getting harder for even the largest chipmakers to st... » read more

Photonics Moves Closer To Chip
By Ed Sperling - 20 Jun, 2016 - Comments: 0

Silicon photonics is resurfacing after more than a decade in the shadows, driven by demands to move larger quantities of data faster, using extremely low power and with minimal heat. Until recently, much of the attention in photonics focused on moving data between servers and storage. Now there is growing interest at the PCB level and in heterogeneous multi-chip packages. Government, academi... » read more

Tiny lasers on silicon A group of scientists from Hong Kong University of Science and Technology, the University of California, Santa Barbara, Sandia National Laboratories, and Harvard University were able to fabricate tiny lasers directly on silicon. To do this, they first had to resolve silicon crystal lattice defects to a point where the cavities were essentially equivalent to those gr... » read more

Addressing The Challenges Of Photonic IC Design Via An Integrated Electronic/Photonic Design Automation Environment
By Cadence - 11 May, 2016 - Comments: 0

Photonics—the science and technology of generating, controlling, and detecting light—is transitioning quickly into mainstream electronic designs. Photonic IC (PIC) design does, however, come with some unique challenges in areas including layout, error checking, and circuit modeling. While electronic designers would have expertise in using a traditional electronic design automation (EDA) flo... » read more

Power/Performance Bits: April 26

An on-chip light source Researchers at the Karlsruhe Institute of Technology (KIT) demonstrated that carbon nanotubes are suited for use as an on-chip light source. By integrating tiny carbon nanotubes into a nanostructured waveguide, the team developed a compact miniaturized switching element that converts electric signals into clearly defined optical signals. "The nanostructures act lik... » read more

Power/Performance Bits: March 29
By Jesse Allen - 29 Mar, 2016 - Comments: 0

Photonic-phononic circuit Researchers at the National Institute of Standards and Technology (NIST) developed a piezo-optomechanical circuit that converts signals among optical, acoustic and radio waves. At the heart of the piezoelectric optomechanical circuit is an optomechanical cavity, which consists of a suspended nanoscale beam. Within the beam are a series of holes that act like a ha... » read more

Multi-Beam Market Heats Up
By Mark LaPedus - 17 Mar, 2016 - Comments: 3

The multi-beam e-beam mask writer business is heating up, as Intel and NuFlare have separately entered the emerging market. In one surprising move, [getentity id="22846" e_name="Intel"] is in the process of acquiring IMS Nanofabrication, a [gettech id="31058" t_name="multi-beam e-beam"] equipment vendor. And separately, e-beam giant NuFlare recently disclosed its new multi-beam mask writer t... » read more

Speeding up optical networks A tunable filter for high-capacity optical networks that can be integrated onto a photonic chip has been designed by researchers at the Université Laval in Québec, Canada. The device's performance is comparable to the best bench-top systems, according to the reasearchers, but at a fraction of the size and cost. The filter's tuning span, which is a measure of... » read more
