Sf. Lim et al., VERTICAL-CAVITY LASERS WITH AN INTRACAVITY RESONANT DETECTOR, IEEE journal of selected topics in quantum electronics, 3(2), 1997, pp. 416-421
We demonstrate the first intracavity quantum-well photodetector within
a VCSEL for top- and bottom-emitting structures, Minimal spontaneous
emission is detected by the internal detector, Dark current is on rite
order of picoamperes, limited by our instrument noise Boor, The inter
nal defector demonstrates high insensitivity to external ambient light
as compared to an external detector, Combining various measurement te
chniques, we gain an understanding of such an integration and discuss
the various ramifications of the issues surrounding the design, fabric
ation, and performance of these integrated VCSEL-detectors, This confi
guration facilitates flexible tailoring of the laser efficiency and th
e integrated detector responsivity.
