Abstract

A photonic MOSFET includes a semiconductor laser in the drain region, and a photon sensor or avalanche photo diode (APD) in the channel / well region. The MOSFET, laser, and photon sensor are fabricated as one integral transistor. When a voltage is applied to the MOSFET gate, and a voltage is applied to the laser, both MOSFET and laser are switched to on. Light emitted from the laser is absorbed by the photon sensor or APD to generate a light current, which flows into the MOSFET drain. This forms a positive feedback control loop. When the MOSFET is turned off, both laser and APD are turned off. A photonic CMOS QCL is regulated by a MOSFET, which operates with electric fields, and avalanche breakdown (with APD), which also depends on electric fields. A traditional QCL is based on quantum well diodes, which rely on thermal diffusion to function, and can be easily affected by temperature variations. In this paper we discuss advantages of photonic CMOS QCL vs. traditional QCL.
