Implementation of a Paraxial Optical Propagation Method for Large Photonic Devices
Published in 2009
We demonstrate the use of COMSOL Multiphysics with MATLAB to model signal generation in wide-bandgap semiconductor radiation detectors. A quasi-hemispherical detector design is compared with a simple, planar detector. Results show that the quasi-hemispherical design can simply and effectively compensate for the poor hole transport of most compound semiconductor materials. In this paper we present an implementation of a BPM-like method in COMSOL Multiphysics and demonstrate its application to several common photonic devices.
