InGaAsP photonic band gap crystal membrane microresonators


We have microfabricated two-dimensional (2D) photonic band gap structures in a thin slab of dielectric material to define reflectors and high-Q microresonators. By selectively omitting holes from the 2D photonic crystal, optical microcavities, and in-plane microresonator switches can be defined. We have designed this structure with a finite difference time domain approach, and demonstrate the effect of lithographic 2D band gap tuning on the emission spectra of InGaAs/InGaAsP multiple quantum well material emission wavelength of 1.55 µm.
