Abstract
On the base of a physico-mathematical model of ion exchange and field-assisted ion migration in glasses, with the use of a beam propagation method and mode analysis, simulations with subsequent fabrication of photonic integrated circuits in K-8 domestic optical glass operating at a wavelength of 1550 nm, have been performed. The main passive waveguide components, including single-mode waveguide dividers of optical signals, directional couplers, polarization converters, etc., have been fabricated and studied. Multichannel waveguide splitters of optical beams and matrices (512 × 512 pcs) of long-focal plane-convex microlenses for Shack-Hartmann wavefront sensors have been created by the method of field-assisted ion migration in glass substrates.
