The silicon typically lies on top of a layer of silica in what (by analogy with in We discuss on-chip light sources with gain materials, linear electro-optic modulators using electro-optic materials, low-power piezoelectric tuning devices with piezoelectric materials, highly absorbing materials for on-chip photodetectors, and ultra-low-loss optical. Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. The rapid evolution of integrated photonics has ushered in a transformative era for optical communication and information processing systems, with silicon-based optical chips emerging as a cornerstone technology.
