Silicon Photonics Manufacturing Ramps Up
By Gregory Haley - 21 Mar, 2024 - Comments: 0

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

Silicon Thermo-Optic Switches with Graphene Heaters Operating at Mid-Infrared Waveband
By Technical Paper Link - 30 Mar, 2022 - Comments: 0

Abstract "The mid-infrared (MIR, 2–20 μm) waveband is of great interest for integrated photonics in many applications such as on-chip spectroscopic chemical sensing, and optical communication. Thermo-optic switches are essential to large-scale integrated photonic circuits at MIR wavebands. However, current technologies require a thick cladding layer, high driving voltages or may introduce h... » read more
