|
The purpose of this study is to solve the problem of optical waveguide shape defects. These defects occur during the process of vertical end face waveguide bridging in photonic chips. The obstruction of the laser beam by the surface of the chip is the root cause of these defects. The present study investigates the light intensity distribution based on the focusing light field of high numerical aperture (NA) lenses. The study focuses on the laser focus at different
