Abstract

We report on linear optical properties of Disperse Red 1 (DR1) doped sol-gel planar and channel waveguides. The refractive index and optical propagation losses of the guiding layer were measured between 0.756 micrometers and 1.64 micrometers . In the telecommunications window, the attenuation is dominated by the overtones of the O-H bonds vibration bands. We also report on photobleached channel waveguides. Propagation losses were measured at 1.064 micrometers as a function of the waveguide width. Attenuation coefficients as low as 1 cm^-1 in 4 to 8 micrometers wide channel waveguides were demonstrated. A good confinement of the light is observed in a 3 hours bleached sample. The suitability of plasma etching as an alternative technique for fabricating channel waveguides is demonstrated.
