We demonstrate experimentally two widely tunable optical couplers formed with parallel
long-period polymer waveguide gratings. One of the couplers consists of two parallel …

We propose a cost-effective narrow bandpass filter based on a guided-mode resonance
(GMR) structure, operating at full conical mounting configuration. Two additional layers …

A long-period waveguide grating in a polymer channel waveguide, which consisted of a
benzocyclobutene core and an epoxy cladding, has been fabricated. By changing the stress …
