About this Research Topic
In the past years, silicon photonics was expected to combine the billion-dollar CMOS industry with optical communication networks. However, recent works prove that this field is becoming much larger than expected. The impact of silicon photonics on optoelectronic integrated circuits, lidar, quantum photonics, and optical biosensing platforms has become so huge so that most of the traditional devices are currently being replaced by their silicon photonic counterparts. Silicon waveguides, passive devices, sensors, and modulators are expanding continuously but creating an integrated light source and photodetector on silicon wafer remains a challenge yet. Currently, integration of photonics and electronics is one of the key subjects on the way to all-optical devices.
The ultimate goal of silicon-based photonic devices is to combine the high yield, mass production, and mature technology of CMOS facilities with the properties of photonics. These properties include high-speed modulation and high bandwidth with an aim of 1 Tb/s data transmission speed, extremely high sensitivity for biosensors with single-particle detection capabilities, low loss and small footprint for passive devices and electromagnetic interference-free operation, extremely low power consumption. Combining the light-source, optical link, modulator, and photodetector, with an electronic read-out platform all on the same chip, most commonly on a silicon on insulator (SOI) platform, remains one of the major challenges.
