| dc.description.abstract | The influence of the limited acceptance angle of a
high-finesse microcavity two-photon absorption photodetector on
its response has been investigated. It is shown that the limited
acceptance angle of the microcavity explains the observed asymmetry
seen in the spectral dependence of the microcavity. The
theory describing the influence of the acceptance angle allows for
an optimum incident beam waist for any cavity structure to be
calculated, with an optimum spot diameter of 7?m having been
calculated for the microcavity under test. The theory also enables
the calculation of an optimum incident spot size for any microcavity.
It is shown that a cavity with higher overall reflectivity
require larger input spot sizes in order to optimize the level of
generated two-photon absorption. | en |
