Paper Abstract

We have evaluated the resonant photodetection characteristics of long wavelength double fused InGaAsP/AlGaAs vertical cavity lasers. Using VCSEL structures fabricated by the localized fusion technique for laser generation, light detection is also possible in open circuit, short circuit and forward biased (FB) regimes. The wavelength selectivity of the detection increases with driving current in FB regime. Detection spectrum with FWHM as low as 0.02 nm is demonstrated in the FB regime at currents above threshold. Investigated structures emit and detect light with high spectral selectivity and may be very useful as multifunctional elements for signal generation a d detection in wavelength division multiplexing systems.
