Abstract

The corrugated waveguide parameters and the threshold current densities of the TE and TM modes in InGaAsP/InP lambda /4-shifted DFB lasers with non-reflective ends were calculated and the TE/TM ratio over 30 db was obtained. Experimental TE/TM ratios of about 35 db in a directly modulated condition are reported.
