Abstract:
Two-dimensional photonic crystals etched into GaAs/AlGaAs waveguides have been investigated by means of second-harmonic generation (SHG) from the surface of the samples. 130-fs laser pulses from a tunable Ti:sapphire source at 800 nm and from an optical parametric oscillator in the range 1.4-1.6 micron have been chosen to excite SH signals in reflection and diffraction directions. Their observed behavior reflects the GaAs crystalline symmetry and the photonic crystal structure, respectively.
