Abstract

We configure a mode converter for the conversion of the higher-order mode (TE1) output from deep-etched laterally-coupled distributed feedback (DFB) laser into the desired fundamental mode (TE0), with a high efficiency of 98.9% at 1310 nm and >95% over the O-band. The whole structure has a compact size of about 25μm in length and exhibits high performance in broad bandwidth and low insertion loss.
