Abstract

We have developed eight-DFB-LD-array WSLs having a novel integration structure that uses a selectively-grown microarray active waveguides directly connected to dry-etched passive waveguides. We have first demonstrated an entire coverage of 100-GHz-spaced 135 ITU-T grids over the S-, C-, and L-bands by using only six WSLs fabricated on two wafers. High device performances such as more than 15-nm Δλ, P_f of over 9 mW, and an SMSR of more than 42 dB were also shown. The practical properties of the WSLs over the three bands will increase the transmission capability of multi band DWDM systems.
