Abstract :
We report on electrically injected coupled resonator vertical-cavity laser (CRVCL) diodes, including two novel modulation approaches. We show a side sketch of the CRVCL which consists of a lower active resonator containing 3 InGaAs quantum wells and a passive upper resonator composed of undoped GaAs. In the bottom active cavity we employ selective oxidation of AlGaAs to form buried oxide layers for efficient electrical and optical confinement. Electrical contacts to each cavity provide independent current injection into the resonators.
