Abstract
The paper deals with analytical investigation of technological equipment tolerance requirements for multiplayer optical waveguides structure creation in monolithic glass substrate by laser-induced clearing of (gamma) -induced color centers. It is proved that autocorrelation interval of waveguide boundary deviation is equal to the step of moving mechanism and is considerably more than signal wavelength. Thus the main scattering mechanism is the axis deviation and the local size varying. We propose the new waveguide creation method in single run of optical system by mean of two laser sources. It allows to reduce the scattering on the local size varying. Theoretical estimation of such waveguide scattering losses is 0.1 dB/cm when the step (tolerance) of laser beam moving is 0.1 micrometers .
