| Brief Research Summary | ||
| My
research experience is in the area of dielectric microcavity lasers.
I studied the directional emission of microcavities with arbitrary
cross sections, where the geometries lead in the semi-classical limit
to mixed-chaotic ray motion (wavechaos). For this project I developed
algorithms to efficiently solve the Helmholtz equation, derived
analytic solutions in the semi-classical limit, and wrote programs to
trace rays in the phase-space picture. Another topic of the
research
was the polarization properties of light in three dimensional
microcavities, where the polarization degree of freedom adds a vector
component to the chaotic dynamics. In addition I worked in Richard
Chang's lab on imaging the emission of GaN microcavity lasers and
analysing the lasing whispering gallery modes of a smooth triangular
shaped GaN microcavity laser. |
