Abstract

Organic laser dye doped Zirconia-Titania-ORMOSIL waveguide thin films with refractive index from 1.55 to 1.59 were prepared by the sol-gel method. The thickness can be varied from 0.97 μm to 10 μm by changing coating speed. Distributed feedback waveguide lasing with multi-wavelength were observed with a periodic gain modulation induced by a frequency-doubled Nd:Yttritium-aluminum-garnet (YAG) laser. Wavelength tuning typically from 597 nm to 602 nm was demonstrated in Rhodamine 6G doped multiple mode waveguiding ZrO₂-TiO₂-ORMOSIL thin films DFB configuration by varying the temperature from 20°C to 120°C. The thermal coefficients of DFB waveguide laser wavelength and the refractive index of the film were deduced. This compact DFB laser device can be applied to measure the thermal coefficients of refractive index of the active films, and used as a remote temperature sensor.
