Grating photomodulator
WebJan 15, 2024 · SILICON PHOTOMODULATOR DESIGN We begin by studying the modulation obtained from a single silicon wafer in isolation. We define the modulation of a reflected beam, M R, as the difference in the reflected intensity when the silicon is dark, R dark, and illuminated, R illuminated: M R = R dark − R illuminated.
