TUNABLE LASER USING III-V GAIN MATERIALS

摘要

Disclosed herein are techniques, methods, structures and apparatus that provide a laser monolithically integrated in a silicon photonic integrated circuit (PIC) that is suitable for high-performance coherent fiber-optic telecommunications and other applications. Among the features of a laser according to the present disclosure, and in particular a hybrid InGaAsP/Si laser, is an integrated Si isolator to protect the laser from back reflections; optical, rather than electrical pumping; and coupling the optical pump using an InGaAsP grating coupler that acts simultaneously as a WDM coupler and laser mirror.

1. A optically pumped, III-V silicon laser comprising:
a laser element having a gain medium disposed within a laser cavity that generates laser light in response to pump light; a grating coupler for coupling the pump light emitted by a pump laser to the laser element; wherein said grating coupler operates as a laser cavity mirror and pump coupler.
