Tunable light propagation in Y-shaped waveguides in two-dimensional photonic crystals composed of semiconductors depending on temperature

We theoretically demonstrate the tunability of light propagation in Y-shaped waveguides in two-dimensional photonic crystals composed of semiconductors that depend on temperature. Refractive indices of semiconductors for light near the plasma frequency can be changed under the influence of temperature. Thus, we can control the direction of light propagation in Y-shaped waveguides in two-dimensional photonic crystals, which may provide novel application of waveguides.
