abstract
A compact optical element integrating a hollow waveguide and a photonic band-gap structure is created by combining a diffraction grating and a mirror. This element offers much promise for various applications in nonlinear and ultrafast optics. The main features of experimental transmission spectra of such waveguide structures are qualitatively interpreted in terms of the coupled-mode theory. Localization of light near the surface of a metal-coated grating in lowest order TM modes in the created waveguide enhances effects related to the photonic band-gap structure.
