Abstract
An optical coupler was designed and fabricated based on multimode interference (MMI) within the InP/InGaAsP Multiple Quantum Well (MQW) structure for use at the 1.55-μm wavelength. A theoretical analysis of MMI is presented by using the beam propagation method (BPM). The MMI section was designed to be a rib-type waveguide by using the effective refractive index method. A 2 × 2 optical coupler, which has a rib-type waveguide foi the MMI section, was fabricated and tested. It showed a good self-imaging property, which is the characteristic of the MMI effect.
