Abstract

Microdisk lasers are promising components for VLSI photonic integrated circuits (PIC), because of their small footprint and ease of fabrication. However, until now output powers remain quite low. In this paper we investigate the loss contributions of the top and bottom metal contact in a 2D axisymmetric FEM simulation. The coupling efficiency from the microdisk laser to an underlying waveguide is also investigated with 3D FDTD simulations. Optimum values for the contacts and coupling parameters are found and can be used to improve the design of microdisk lasers.
