Optical manipulation of guided mode resonance in azo-copolyme waveguide gratings


Optical tuning of guided mode resonance (GMR) is demonstrated in an azo-copolymer waveguide grating structure (WGS), comprised of a one-dimensional holographic surface relief grating inscribed on top of an azo-copolymer planar waveguide layer. The resonance wavelength of GMR is blue-shifted by pumping the WGS with a linear polarized laser beam at 514 nm as… (More)
