Observation of light propagation in photonic crystaloptical waveguides with bends

Observation of light propagation in photonic crystal optical waveguides with bends Light propagation is investigated in two-dimensional photonic crystal waveguides with bends, which were composed of closely-packed holes formed in a GaInAsP thin film. Wavelength and polarisation dependence on propagation characteristics were observed in the wavelength range 1.47–1.60 µm.
