Silicon Photonics: Solving Process Variation And Manufacturing Challenges
By Sandy Wen - 17 Aug, 2017 - Comments: 0

As silicon photonics manufacturing gains momentum with additional foundry and 300mm offerings, process variation issues are coming to light. Variability in silicon processing affects the waveguide shape and can result in deviation in effective indices, propagation loss, and coupling efficiency from the intended design. In this article, we will highlight process variation issues that can occur i... » read more

The Great Machine Learning Race
By Ed Sperling - 03 Apr, 2017 - Comments: 2

Processor makers, tools vendors, and packaging houses are racing to position themselves for a role in machine learning, despite the fact that no one is quite sure which architecture is best for this technology or what ultimately will be successful. Rather than dampen investments, the uncertainty is fueling a frenzy. Money is pouring in from all sides. According to a new Moor Insights report,... » read more

Analog’s Rising Status
By Ann Mutschler - 08 Dec, 2016 - Comments: 1

As more sensors and actuators are added into electronic devices, pressure is growing to more seamlessly move data seamlessly back and forth between analog and digital circuitry. [getkc id="37" kc_name="Analog"] and digital always have fit rather uncomfortably together, and that discomfort has grown as [getkc id="81" kc_name="SoCs"] are built using smaller feature sizes. While digital transis... » read more

Another record-breaking tandem perovskite solar cell University of California, Berkeley, and Lawrence Berkeley National Laboratory scientists report a new design for perovskite solar cells that achieves an average steady-state efficiency of 18.4%, with a high of 21.7% and a peak efficiency of 26%. "This has a great potential to be the cheapest photovoltaic on the market, plugging into any... » read more

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

Power/Performance Bits: June 7

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
