Abstract

Antiresonant reflecting optical waveguides (ARROW) [1] are of current interest both in passive and active optical devices. These guides have unique properties when compared to conventional structures based on total internal reflection. They offer low loss, polarization and wavelength selectivity as well as easy of fabrication. The refractive index and size of the core layer allow flexibility in coupling to an optical fibre with minimal loss. The fact that ARROW guides can be implemented on semiconductor substrate makes them ideal for integration with electronic devices on a single chip.
