Abstract :
We developed multi-range wavelength-selectable light sources (WSLs) with an all-selective MOVPE (ASM) grown microarray planar-buried-hetero (MPBH) structure. We simultaneously fabricated five WSLs, each with a unique 8-nm tuning range, to cover forty 100-GHz-spaced channels (the entire C-band). Uniform characteristics, such as an I/sub th/ of 8.3 /spl plusmn/ 1.2 mA, an SMSR of over 45 dB, and a fiber-coupled power up to 15 mW, were obtained.
