Popis:	Permanent photo induced refractive index changes by means of UV exposure have been used for laser trimming, fabrication of Bragg gratings [1] and direct writing of channel waveguides [2]. Direct writing is particularly attractive since it allows two-dimensional light confinement without the expensive and time consuming dry-etch stage. In this paper we report on the simultaneous production of both a 2-D waveguide and a Bragg grating.
