G02B6/29335 - CPC Classification

Classification description:

Light guides; Coupling light guides; Optical coupling means having data bus means, i.e. plural waveguides interconnected and providing an inherently bidirectional system by mixing and splitting signals with wavelength selective means operating by evanescent wave coupling Evanescent coupling to a resonator cavity, i.e. between a waveguide mode and a resonant mode of the cavity
