GaAs-based grating system for Q-switching on the basis of IMOS structure

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

GSolver software is used to optimize the
parameters of a GaAs-based layers structure for modulating the
reflectivity of light. This structure can be used in an Integrated
Mirror Optical Switch (IMOS) for the Q-switching technology. A
system of low doped GaAs and highly doped AlGaAs structure is
built on a binary diffraction grating composed of germanium and
gold. The diffraction efficiency is determined with and without
the existence of free carriers in the highly doped layer. The
impact of the sheet charge density at the interface of the
heterostructure is considered in determining of the diffraction
efficiency. At the end of the study, the structure parameters and
thicknesses are determined for a high sensitive device.
