Polymer photonic crystal band edge lasers for evanescent wave sensing

Abstract

Two different effects of optofluidic tuning of polymer photonic crystal band edge lasers are demonstrated. A device symmetry different from that of the photonic crystal is imposed by the global shape of the device. This causes the device to emit in fewer directions, and the relative intensities of these signals depend on cladding refractive index. The wavelength of the emission in any direction depends on cladding refractive index with a sensitivity of 1 nm per 102 refractive index units.
