New configurations for polymer-based multilayered grating-waveguide structures whereby the waveguide layer is spun-coated over a Si substrate and the grating layer is obtained by holographic recording, are presented. Such structures are demonstrated

Promising configurations for dual spectral filters based upon grating-waveguide structures are presented. In these configurations, the parameters of the multimode waveguide and grating are carefully chosen to achieve dual resonances at two different

When illuminated with an incident beam of light, grating waveguide structures (GWS), of specific geometrical and optical parameters, have a resonant behavior. Under such behavior, an incident beam, which is normally completely transmitted, is wholly

Promising configurations for grating-waveguide structures are presented. In these structures, the grating layer, which is normally adjacent to the waveguide layer, is displaced by means of an intermediate layer, resulting in significant reduction of

The research of passive and active grating waveguide structures has been ongoing in our group for the last decade. We briefly review recent research activities, emphasizing how such structures can be exploited for optical communication and for biolog

Under certain conditions, a high-finesse resonance phenomenon can occur in a grating waveguide structure (GWS). By varying these conditions, a shift in the resonance wavelength can be achieved. Specifically, utilizing the high finesse property of the

When a grating-waveguide structure is illuminated with an incident light beam at a specific wavelength and angular orientation, a resonant phenomenon occurs. The resonance spectral bandwidth can be very narrow, so the structure can serve either as a
