Remote Coupling in a Rib Arrow Coupler
Almost a decade ago a novel guiding scheme which relies on resonance effects such as one finds in Fabry-Perot resonators could be identified1. Those so-called Anti-Resonant-Reflecting-Optical-Waveguides (ARROWs) did not attract a considerable attention among the waveguide community until recently. They exhibit several striking peculiarities as quasi-monomode behavior, particular dispersion relations that can be exploited to implement attractive devices as e.g. remote couplers2 ,remote switches3, polarizers4, polarization splitters and extremely narrow-band wavelength filters.
