title: 2D Photonic crystal thermo-optic switch based on AlGaAs/GaAs epitaxial structure.
abstract: The realisation of a thermo-optically controlled symmetric Mach- Zehnder interferometer switch based on an AlGaAs/GaAs epitaxial waveguide structure operating at wavelengths in the region of lambda = 1550 nm is reported. The device is based on a very compact two-dimensional photonic crystal channel waveguide structure. The measured and simulated transmission spectra for the devices are in good agreement. The Pi-phase shift switching power for the device is as low as 42 mW.
