Abstract
A surface plasmon-based photodetector includes: a silicon substrate; a grating in contact with a surface of the silicon substrate, in which the grating forms a Schottky diode with the semiconductor substrate; and a complementary-metal-oxide-semiconductor (CMOS) sample and hold stage as well as an analog-to-digital circuit (ADC) in the silicon substrate and arranged to detect electrical current generated at the Schottky diode.
