Abstract

Graded Refractive-index Embedded Core Optical (GRECO) waveguides have been realized in GaAs/GaAlAs by sequential introduction of superlattice periods during OMCVD growth on patterned substrates. This novel technique offers the possibility of synthesising the vertical index profile of the core and provides a built-in index difference for lateral confinement of guided modes. Fully planarized waveguides have been fabricated with propagation losses of 1.5dB/cm at k= 1.52 vim and their field distribution has been analysed using a finite element technique.
