ABSTRACT: We developed high-performance distributed feedback array-based wavelength-selectable light sources (WSLs), covering the entire C-band with five simultaneously fabricated devices. We fabricated five different range WSLs on a wafer, each with a unique 8-nm tuning range to cover 40 100-GHz-spaced channels. Uniform characteristics, such as an Ith of 8.3/spl plusmn/1.2 mA, a sidemode suppression ratio of over 45 dB, and a fiber-coupled power greater than 8.5 mW were obtained.

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.

ABSTRACT: We have developed a wavelength-selectable light source (WSL) based on microarray DFB-LD configuration that enables high fiber-coupled power operation. The WSL was grown in only two steps without any complicated semiconductor etching. Using the WSL, fiber-coupled power of more than 20 mW and stable single-mode oscillations with an SMSR of more than 50 dB were obtained for all 23 addressable ITU-T channels on a 50-GHz grid.
