Optically-pumped long-wavelength vertical-cavity surface-emitting laser with high modulation bandwidth

摘要

Optically-pumped long-wavelength vertical-cavity surface-emitting lasers (VCSELs) have been fabricated exhibiting more than 2 mW over 20-70℃, and 1.25 mW at 85℃. Small-signal modulation measurements on the VCSEL at 20℃ indicate a 3 dB bandwidth of 14.8 GHz at an output power of 2 mW. The VCSELs have a narrow spectral width suitable for data transmission over single-mode fiber. The good temperature performance of the VCSEL is maintained in a suspended configuration that would allow monolithic integration.
