dc.description.abstract | The most important feature of a two-photon absorption microcavity (TPAM) is
that of its enhancement of the optical field which enhances the level of twophoton
absorption (TPA) for a particular input optical power incident on the
detector. The TPAM is shown to not only enhance the level of TPA but also to
suppress the level of residual single photon absorption (SPA) relative to the level
of TPA. This allows a TPA dominated signal to be accessed at much lower
incident optical powers than would be possible for a similar GaAs absorbing
region which was not sandwiched between two highly reflective distributed
Bragg retlectors (DBR's). The TPA coefficient is estimated to be approximately
15 cm/GW at 1560 nm in (001) GaAs. The residual SPA coefficient in the
unintentionally doped GaAs active layer of the TPAM (which is grown by metalorganic
chemical vapour deposition) is approximately 1.0 x 10 -4 cm -1. | |
