Increasing the coupling efficiency of a microdisk laser to waveguides by using spiral structures

Liu, Danyu; Hattori, Haroldo; Fu, Lan; Jagadish, Chennupati; Tan, Hark Hoe

Description

In this article, we show that the introduction of a spiral waveguide to a GaAs microdisk that works both as a waveguide and circular Bragg reflector can improve coupling efficiency to almost 90%. The same structure with the addition of a taper can couple
