Abstract:

This chapter describes our progress to date in the growth of thin film optical waveguides using both single-beam and multiple-beam/multiple-target geometries using single-crystal garnet targets. More than one target offers the possibility of tuning both the optical and physical properties of the films produced via control of the temporal sequencing of the laser plumes from separate targets. Mixed, layered and superlattice growth, which involve vertical engineering of the film structure, allow precise control of the refractive index profile, a fundamental parameter in the design ...
