We report simultaneous second-harmonic generation (SHG) and third-harmonic generation (THG) in photonic crystals slabs (PCS) by strongly coupling fundamental light into waveguide modes. The spectra of the SHG and THG signals are investigated as a function of both the wavelength and the polarization state of the fundamental beam. The second-order nonlinearity obtained in the PCS can be comparable with...
Microtube-Czochralski technique was employed to grow large size benzophenone single crystal for the first time. In conventional Czochralski pulling technique, the growth of bulk single crystal will be initiated by a pre-grown seed, whereas in microtube-Czochralski technique a microtube that is made out of a metal such as stainless steel (8μm ID) can be used to grow bulk single crystal. A specially...
