Abstract

Described herein is a two chip photonic device (e.g., a hybrid master oscillator power amplifier (MOPA)) where a gain region and optical amplifier region are formed on a III-V chip and a variable reflector (which in combination with the gain region forms a laser cavity) is formed on a different semiconductor chip that includes silicon, silicon nitride, lithium niobate, or the like. Sides of the two chips are disposed in a facing relationship so that optical signals can transfer between the gain region, the variable reflector, and the optical amplifier.
