Optical coupling between a two-dimensional photonic crystal-basedmicrocavity and single-line defect waveguide on InP membranes

摘要

We demonstrate the mutual coupling between a microcavity and anwaveguide realized in a two-dimensional photonic crystal on an InPnmembrane. Coupling processes are evidenced by generating guided orncavity modes by photoluminescence and by measuring locally thendiffraction losses. Depending on the transfer and loss dynamics,ndifferent coupling processes are found. Finite difference time-domainnsimulations and additional polarization resolved luminescencenmeasurements are performed in order to further investigate the couplingnprocedure
