Popis: | We report on the fabrication and characterization of light-emitting diodes (LEDs) and laser diodes with a staggered type II Ga1−xInxAs/GaAs1−ySby superlattice (SL) as the active region. SLs were grown strain compensated on the InP substrate using metalorganic chemical vapor deposition. The LEDs show room-temperature electroluminescence up to 2.14 μm, the index-guided diode lasers displayed cw laser emission at 1.71 μm up to 300 K. The spontaneous emission spectrum was found to show a significant blueshift with increasing injection current density, resulting in shorter laser emission wavelengths for the diode laser than for the LED. |
