| Abstract: | A new 1.55 ?m wavelength GaInAsP laser is described: the multisection ridge laser. Pulsed thresholds were typically 40?80 mA. CW thresholds were comparable. The lowest measured CW threshold was 38 mA at 12°C. The laser operated stably in a single longitudinal mode (spurious modes down by ?16 dB) under fast pulse modulation with a prebias below threshold. Theoretical results based on a waveguide scattering theory are in qualitative agreement with the experimental results. |
