Silicon Photonics Manufacturing Ramps Up


Circuit scaling is starting to hit a wall as the laws of physics clash with exponential increases in the volume of data, forcing chipmakers to take a much closer look at silicon photonics as a way of moving data from where it is collected to where it is processed and stored. The laws of physics are immutable. Put simply, there are limits to how fast an electron can travel through copper. The... » read more

An All-Optical General-Purpose CPU And Optical Computer Architecture (Akhetonics)


A technical paper titled “An All-Optical General-Purpose CPU and Optical Computer Architecture” was published by researchers at Akhetonics. Abstract: "Energy efficiency of electronic digital processors is primarily limited by the energy consumption of electronic communication and interconnects. The industry is almost unanimously pushing towards replacing both long-haul, as well as local c... » read more

A Solver Combination Strategy For Photonic Integrated Components


With the increasing demand for optical bandwidth, photonic integrated circuit (PIC) technology is undergoing a growth rate very similar to the one seen by electronic integrated circuits over the last half-century. To keep up with the increasing number of components and circuit complexity, efficient and reliable automated design tools are necessary to carry out virtual prototyping, improve yield... » read more

Neuromorphic photonic circuit modeling in Verilog-A


Abstract "One of the significant challenges in neuromorphic photonic architectures is the lack of good tools to simulate large-scale photonic integrated circuits. It is crucial to perform simulations on a single platform to capture the circuit’s behavior in the presence of both optical and electrical components. Here, we adopted a Verilog-A based approach to model neuromorphic photonic cir... » read more
