Two-photon absorption in microcavities for optical autocorrelation and sampling.
In: CLEO/Europe 2003 Conference on Lasers and Electro-Optics Europe, 22-27 June 2003.
We have designed novel semiconductor microcavity structures for the enhancement of the two-photon absorption (TPA) photocurrent. We report a TPA autocorrelation technique for short optical pulses that uses the microcavity structure instead of a second harmonic generation crystal. Knowledge of these characteristics is important for implementation in applications such as optical switching and sampling in optical time division multiplexed (OTDM) communications systems.
