Low-threshold in AlGaAs vertical cavity suface-emitting laser arrays using transparent contacts.
We present top-emitting all-epitaxial planar laterally oxidized vertical-cavity surface-emitting lasers employing transparent indium-tin-oxide electrodes. The transparent contacts facilitate device fabrication and offer significantly denser device packing than similar planar laterally oxidized structures using metal contacts. The InAlGaAs-based devices operate at a wavelength of 817 nm with a minimum threshold current of 175 µA.
