Polarization dependence of a GaAs-based two-photon absorption microcavity photodetector.

چکیده
In this paper, the polarization response of a GaAs based two-photon absorption microcavity photodetector has been studied. The deviation in the dependence of the detector response from that of bulk GaAs is shown to be due to the birefringence of the cavity. A theoretical model based on the convolution of the cavity birefringence and the polarization dependence of two-photon absorption in GaAs is described and shown to match the measured polarization dependence of the microcavity detector very well.

Temperature tuning of two-photon absorption microcavity photodetectors for wavelength selective pulse monitoring
Introduction: Two-photon absorption (TPA) has recently received attention with optical performance monitoring of group velocity dispersion, polarisation mode dispersion and optical signal-to-noise ratio having been demonstrated [1, 2]. TPA is a weak, nonlinear process and as such is inefficient. A number of different detectors have previously been used to overcome the low level of TPA in semico...

Future high-speed optical communications networks operating at data rates in excess of 100Gbit/s per channel will require a sensitive and ultrafast technique for precise optical signal monitoring. The standard way of characterising high-speed optical signals to use a fast photodetector in conjunction with a high-speed oscilloscope. However, this method is limited to a maximum data rate of appro...

In this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled InAs/GaAs quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. The microcavity wafer sample is grown by molecular beam epitaxy (MBE) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...

متن کاملTwo-photon absorption photocurrent enhancement in bulk AlGaAs semiconductor microcavities
We report on two-photon absorption ~TPA! photocurrent in semiconductor microcavities. We experimentally show a substantial increase in the TPA photocurrent generated, at resonance, in a GaAlAs/GaAs microcavity designed for TPA operation at ;890 nm. An enhancement factor of ;12 000 of the photocurrent is obtained via the microcavity effect, which could have an important impact on the use of TPA ...
