Abstract
We report the realization of both high contrast ratio (66:1) and dynamic range (30%) at room temperature in a strained GaAs/InGaAs(100) multiple quantum well based asymmetric Fabry–Perot reflection modulator. The p‐i‐n configuration modulator also acts as a photodetector and exhibits a high quantum efficiency (∼80%).Keywords
