Krug, T., Lynch, M., Bradley, A.L., Donegan, J.F., Barry, L.P., Folliot, H., Roberts, J. S., Hill, G. 'High sensitivity two photon absorption microcavity autocorrelator' in Photonics Technology Letters, 16, 2004, pp. 1543 – 1545.
A GaAs–AlAs microcavity device has been used
as a photodetector in an autocorrelator for measuring the
temporal pulsewidth of 1.5- m optical pulses. Enhancement of
the two-photon absorption photocurrent due to the microcavity
structure results in an autocorrelation (average power times peak
power) sensitivity of 9 3 10 4 (mW)2, which represents
two orders of magnitude improvement when compared with
