Abstract

In this paper, the efficiency of extracting light from the minor surface arc of the elliptical microcavity is investigated. The dynamic thermal equilibrium medium FDTD (DTEQM-FDTD) model is used to the field distribution and amplitude in the microcavity under electrical pumping. Light energy is extracted from minor surface arc of the elliptical microcavity to a waveguide. It is deduced from the field that extraction efficiency of TM polarization is due to wider transverse field profile. Optimum light is extracted when the waveguide is 125 nm away from edge of the elliptical minor arc. Higher extraction efficiency also obtained when the waveguide index is lower than the index. It is believed that this method of extracting energy allows for smaller device size with higher power output for building photonic integrated circuit.
