Notes:
We discuss a buried oxide layer forming a current aperture in a vertical-cavity surface-emitting laser. The current spreading under the oxide current aperture leads to high threshold and dual-longitudinal-wavelength characteristics. One is the as-grown cavity resonance and the other is the resonance wavelength under the oxide layer. This structure exhibits (approximately-greater-than)30 dB side-mode suppression throughout its operating range. Meanwhile, a single-longitudinal-wavelength laser with a minimized current spreading has a low threshold current of 85 μA and several nonlasing modes. © 1996 American Institute of Physics.
