| 英文摘要 | A strip buried double heterostructure laser having a pair of opposite-conductivity-type, wide bandgap cladding layers separated by a narrower bandgap active region. The active region includes a low-loss waveguide layer and contiguous therewith a narrower bandgap active layer in the form of a narrow strip extending along the longitudinal (resonator) laser axis. Lateral current confinement means, such as reversed biased p-n junctions, constrain pumping current in a narrow channel through the active layer. Lasers of this type exhibit relatively high pulsed power outputs (e. g., 400 mW), linear L-I characteristics, stable fundamental transverse mode and single longitudinal mode oscillation. In another embodiment waveguide layer surfaces adjacent the active layer have distributed feedback gratings. Also described are techniques for shaping the active layer without introducing debilitating defects therein, as well as procedures for LPE growth on Al-containing Group III-V compound layers which are exposed to processing in the ambient. |
