Paper Abstract

In this paper we demonstrate how an elliptically shaped semiconductor microcavity can be used to generate surface plasmons (SP) mode by pumping current and injecting optical pulse. After achieving stable lasing mode, external magnetic field is applied to a small elliptical confined area on the elliptical microcavity. The applied magnetic field produces Lorentz torque and "pushes" the electrons to the edge of the microcavity. Strong electron plasma is built up on the boundary of the microcavity and air interface as more electrons accumulate. The laser light source interacts with the electron plasma at the boundary of microcavity and excites surface plasmon mode. The direct excitation of SPP modes could be used to extract the laser light from elliptical microcavity source and results in a lower coupling loss and higher efficient small coupling system.
