O. Sjolund et al., MONOLITHIC INTEGRATION OF MICROLENSED RESONANT PHOTODETECTORS AND VERTICAL-CAVITY LASERS, Electronics Letters, 34(18), 1998, pp. 1742-1743
Monolithic integration of high performance microlensed resonant photod
etectors and vertical cavity lasers (VCLs) from a single epitaxial gro
wth is presented. The VCLs have sub-200 mu A threshold currents. Adjac
ent detectors have the same operating wavelength and responsivities of
similar to 0.4A/W with similar to 6nm optical bandwidths.
