This paper presents a detailed experimental and theoretical study of the properties of deep-etched GaAs-AlGaAs optical waveguides designed using a version of the spectral index method which predicts mode losses due to leakage through the lower claddi

The free space radiation mode (FSRM) method is used to provide a new closed-form transcendental equation for the scalar mode propagation constant of a uniformly buried rectangular dielectric waveguide. Results are readily and rapidly obtained and are

We have developed a semianalytical approach to study the propagation characteristics of multimode interference (MMI) waveguide structures. The effect of transverse crosssection geometry on self-imaging length and optical power throughput are investig

A fast and near exact modal analysis is presented to obtain the propagation constants and electric field profiles for dielectric multilayered channel (rib) waveguides. Calculations are performed for a particular channel configuration and found to be

The use of multimode interference (MMI) rib waveguides as couplers/recombiners in passive and active photonic applications has become well established 1,2 and leads to a number of advantages over conventional Y-junction and directional couplers, such

It is often the case that semiconductor rib waveguides are fabricated on substrates with refractive indices that are equal to or larger than those of the principal guiding layers. This is particularly the case in the GaAs/AlGaAs material system (for
