Detector Characteristics of a Vertical-Cavity Surface-Emitting Laser

Abstract
The possibility of using a vertical-cavity surface-emitting laser (VCSEL) as a detector has been investigated. For a 100 Å In0.2Ga0.8As strained quantum-well-layer that serves as both an active and absorption layer, 26% absorption due to the effect of multireflection mirrors and an 8% absorption increase at the resonant wavelength by applying an electric field were demonstrated.
