Chip Sandwich: Electronics Chip & Photonics Chip Co-Optimized To Work Together (CalTech/Univ. of Southampton)


A technical paper titled "A 100-Gb/s PAM4 Optical Transmitter in a 3-D-Integrated SiPh-CMOS Platform Using Segmented MOSCAP Modulators" was published by researchers at CalTech and University of Southampton. "The resulting optimized interface between the two chips allows them to transmit 100 gigabits of data per second while producing just 2.4 pico-Joules per transmitted bit. This improves th... » read more

EDA Tools For Quantum Chips


Commercially viable quantum computers are at least several years away, but some researchers already are questioning whether existing EDA tools will be sufficient for designing quantum chips and systems. That’s because quantum design requirements at times transcend classical rules about materials, temperature, and structure — rules that are foundational for the majority of EDA products on th... » read more

Using Silicon Photonics To Reduce Latency On Edge Devices


A new technical paper titled "Delocalized photonic deep learning on the internet’s edge" was published by researchers at MIT and Nokia Corporation. “Every time you want to run a neural network, you have to run the program, and how fast you can run the program depends on how fast you can pipe the program in from memory. Our pipe is massive — it corresponds to sending a full feature-leng... » read more

New Class of Electrically Driven Optical Nonvolatile Memory


A new technical paper titled "Electrical Programmable Multi-Level Non-volatile Photonic Random-Access Memory" was published by researchers at George Washington University, Optelligence, MIT, and the University of Central Florida. Researchers demonstrate "a multi-state electrically-programmed low-loss non-volatile photonic memory based on a broadband transparent phase change material (Ge2Sb2S... » read more

Research Bits: Oct. 25


Polarization for photonic processor Researchers from the University of Oxford and University of Exeter developed a photonic processor that uses multiple polarization channels, increasing information density. "We all know that the advantage of photonics over electronics is that light is faster and more functional over large bandwidths. So, our aim was to fully harness such advantages of phot... » read more

On-chip 2D/3D Photonics Integration Solution Using Deposited Polycrystalline Silicon for Optical Interconnects Applications


A new technical paper titled "Polycrystalline silicon PhC cavities for CMOS on-chip integration" was published by researchers at Tyndall National Institute, Munster Technological University, and Université Grenoble Alpes, CEA, LETI. "In this work, we present an on-chip 2D and 3D photonics integration solution compatible with Front End of Line integration (FEOL) using deposited polycrystalli... » read more

Week In Review: Manufacturing, Test


President Biden signed an executive order on Sept. 15, limiting foreign investments in U.S. technology by "competitor or adversarial nations" that are deemed a threat to national security. In the past, the Committee on Foreign Investment in the United States (CFIUS) largely limited its actions to the sale of U.S. companies. The new directive expands that to include investments involving "U.S. s... » read more

More Efficient On-Chip Laser Frequency Comb (Harvard)


A new technical paper titled "High-efficiency and broadband on-chip electro-optic frequency comb generators" was published by researchers at Harvard, Stanford, Caltech, and Hyperlight. The research claims the electro-optic frequency device is 100% more efficient and has 2X the bandwidth of previous technology.    According to Harvard's news release, "the latest research applies the two con... » read more

Choosing The Right Photonic Device Design Software


There are many factors to consider before deciding which software to use for photonic device design. To narrow the field, it can be helpful to ask these key questions as you investigate and compare software functionality. • Does the software provide enough flexibility to model and analyze products that offer the best solution to likely and possible design goals? • Is the simulation ca... » read more

CogniFiber: Photonic Computing


Computing with light has many advantages. It's fast, cheap, and it doesn't generate much heat. But it's also difficult to make it work, and it has a number of challenges that are specific to photonics. CogniFiber, an Israeli startup, says it has solved many of these issues. The company uses photonics over fiber, and it has introduced a glass-based chip. “We use light as a data conveyor ... » read more
