Efficient, narrow-linewidth distributed-Bragg-reflector surface-emitting laser with periodic gain

Technical Report ·
OSTI ID:5200932
Efficient, narrow-line emission from a novel vertical-cavity distributed Bragg reflector surface emitting laser (DBR-SEL) with gain segments periodically placed on standing-wave maxima was obtained. Clean single-longitudinal-mode spectra with <2A line widths, sharp output/input characteristics, and thresholds below that of analogous all-GaAs active-region devices were obtained by optical pumping. Theoretical calculations indicate the optimum number of quantum wells and mirror reflectives for best threshold and efficiency.
