Phase-matched second-harmonic generation by eriodic poling of fused silica
90” phase matching in periodically poled fused silica is achieved over approximately 2 mm at a wavelength of 1064 nm. Electrical poling was done at 5 kV for 120 min using photolithographed periodic electrodes on fused silica glass at 250 “C. A nonlinearity equivalent to &/200 of quartz is estimated from measurements. Several phase-matched interactions are reported and the implications for devic...
متن کاملWaveguide electro-optic modulator in fused silica fabricated by femtosecond laser direct writing and thermal poling.
An integrated electro-optic waveguide modulator is demonstrated in bulk fused silica. A Mach-Zehnder interferometer waveguide structure is fabricated by direct writing with a femtosecond laser followed by thermal poling. A 20 degrees electro-optic phase shift is achieved at an operating wavelength of 1.55 microm with an applied voltage of 400 V and an interaction length of 25.6 mm, which corres...
متن کاملLaser-induced periodic annular surface structures on fused silica surface
We report on the formation of laser-induced periodic annular surface structures (LIPASS) on fused silica irradiated with multiple femtosecond laser pulses. This novel morphology emerges after the disappearance of the conventional laser induced periodic surface structures (LIPSS), under successive laser pulse irradiation. It is independent of the laser polarization and universally observed for d...
متن کاملSupercontinuum generation in quasi-phasematched waveguides.
We numerically investigate supercontinuum generation in quasi-phase-matched waveguides using a single-envelope approach to capture second and third order nonlinear processes involved in the generation of octave-spanning spectra. Simulations are shown to agree with experimental results in reverse-proton-exchanged lithium-niobate waveguides. The competition between χ((2)) and χ((3)) self phase mo...
متن کاملGeneration of microstripe cylindrical and toroidal mirrors by localized laser evaporation of fused silica.
We report a new technique for the rapid fabrication of microstripe cylindrical and toroidal mirrors with a high ratio (>10) of the two principal radii of curvature (RoC(1)/RoC(2)), and demonstrate their effectiveness as mode-selecting resonator mirrors for high-power planar waveguide lasers. In this process, the larger radius of curvature (RoC(1)) is determined by the planar or cylindrical shap...
