Abstract: | In this paper, we present highly reliable high-temperature spot-size converter integrated laser diodes (LDs) fabricated using a full-wafer process with dry etching and MOVPE. The lasers lase at 150°C and operate stably for 10,000 h at 85°C and 10 mW. The median lifetime is estimated to be over 105 h. We also demonstrate a novel screening test procedure for a bar configuration of LDs, which can greatly reduce optical module cost. |
