METHOD OF MANUFACTURING DIVIDER IN INTEGRAL OPTICAL SCHEME Russian patent published in 2018 - IPC G02B6/125 

FIELD: optics.

SUBSTANCE: group of inventions relates to integrated optics, and in particular to methods for producing a balanced divider in circuits based on waveguides formed in the volume of a solid-state workpiece by pulsed laser radiation. Method of manufacturing a divider in an integrated optical scheme consists in forming in the dielectric preform a region of interaction between contiguous waveguides. To do this, use a billet of quartz and form a waveguide in its volume with a linear cross-sectional size d=1÷6 microns by focusing pulsed laser radiation with a frequency ƒ=2÷4 MHz and the average power of a single pulse p=50÷500 kW when moving the workpiece relative to the focus of the radiation with a speed of V=0.4÷0.8 mm/sec. At the interaction site, the waveguides are brought closer to the distance of g=1÷2 microns.

EFFECT: expansion of the arsenal of technical tools for creating wide-range integrated optical dividers.
