Color image generation is an important application for amplitude modulators working in the visible spectral range. A suitable candidate is the integrated-optical Mach-Zehnder interferometer in KTP [Ruske et al. 1998]. However. Due to the very small cross section of its singlemode waveguides it can only be used for low power applications. In order to overcome this limitations, we realized a novel modulation device using large cross section waveguides with high optical damage threshold, the so called asymmetric diffraction amplitude modulator (ADAM) [Pertsch and Wachter 1999]. This device is based on a diffraction zone embedded asymmetrically between an input and an output waveguide. In the off-state the light is diffracted asymmetrically because of the reflecting boundary. At the end of the diffraction zone only a negligible fraction of light couples into the output waveguide. To switch the device to the on-state, the refractive index of a barrier region is reduced by applying a voltage to an appropriate pair of electrodes due to the electro-optical effect. This barrier creates a waveguide connecting the input and output.","PeriodicalId":250878,"journal":{"name":"Conference Digest. 2000 Conference on Lasers and Electro-Optics Europe (Cat.

We report on the fabrication of a novel dielectric T-shaped channel waveguide by liquid-phase epitaxy. Two Nd:LiYF/sub 4/ layers were grown on a LiYF/sub 4/ substrate perpendicular to each other forming the letter T in cross section. From the fabrication process, an active layer thickness of approximately 30 /spl mu/m was deduced. The whole structure was overgrown with LiYF/sub 4/. Plane parallel optical grade end faces were prepared by polishing. The LiYF/sub 4/ crystal c-axis was in the plane of the end face parallel to the vertical T-bar. Laser experiments were performed with external plane dielectric mirrors coupled directly to the waveguide end faces. Lasing of the 12.8 mm long waveguide was achieved at 1047 nm under Ti:Al/sub 2/O/sub 3/ longitudinal pumping at 792 nm. Confinement of the laser mode to the T-shaped channel could be demonstrated. However, the maximum output power of 47 mW was achieved at an incident pump power of 600 mW (50% duty cycle) only with the mode located in the vertical bar of the T slightly below the junction. Waveguide losses were estimated to be smaller than 0.8 dB/cm.","PeriodicalId":250878,"journal":{"name":"Conference Digest. 2000 Conference on Lasers and Electro-Optics Europe (Cat.
