Abstract:	We report our recent results on utilization and optimization of the focused ion beam technique for the fabrication of grating structures for potential integrated photonic devices in crystalline KY(WO4)2:Yb3+. The FIB milling procedure for the realization of grating structures in KYW channel waveguides was optimized. Grating structures more than 4 µm in depth with an improved total sidewall angle of 4.3° were achieved by varying dwell time and pixel resolution distribution. Currently optical characterization of the resonator structures for achieving on-chip waveguide lasers is ongoing.
