1.3 µm vertical microcavities with InAs/InGaAs quantum dots and devices based on them

Various structures with optical microcavities and active layers based on InGaAs/GaAs quantum dots MBE-grown on GaAs substrates were studied theoretically and experimentally. LEDs for the 1.3 µm spectral range with narrow spectral characteristics and low light beam divergence were fabricated. Vertical lasing at 1.3 µm was obtained in a structure with oxidized AlO/GaAs mirrors under injection pumping.
