title: Resonant characteristics of multimode interferometer coupled square ring semiconductor resonators.
abstract: This work reports the spectral characteristics of coupled square ring semiconductor resonators. For a single mode operation, the square ring cavities coupled with multimode interferometers (MMIs) are proposed and fabricated using the epitaxial layers of 1.55 microm center wavelength InGaAsP-InP multiple quantum wells. Resonant characteristics can be tailored by varying the parameters of the cavity size or the waveguide width. By using the MMI coupled square ring cavity, a stable single spectral lasing mode was obtained in various combinations of square cavities.
