Loss-reduced Rectangular Ring Laser Based on Active Vertical Coupler through Asymmetric Double Shallow Ridge and ICP/ICP Cascade Etching

Not Accessible

Your library or personal account may give you access

Abstract

Rectangular ring lasers based on an active vertical coupler structure are fabricated through asymmetric double shallow ridge and ICP/ICP cascade etching. 25% reduction of Ith and the single mode operation with SMSR 23dB are achieved.
