Photosensitive post tuning of chalcogenide photonic crystal waveguides
Abstract
<p>We present experimental results on post-tuning the dispersion of a two-dimensional photonic crystal waveguide made from Ge<sub>33</sub>As <sub>12</sub>Se<sub>55</sub> chalcogenide glass by exploiting the material photosensitivity to near-bandgap light. The change in the refractive index and volume of the material in response to exposure to 633nm light resulted in a shift of more than 5nm in the resonant coupling wavelength between a tapered optical fiber and the modes of a W1 waveguide. This represents a first proof of principle demonstration of the photosensitive post-tuning of a planar photonic crystal device.</p>
