Optical beam steering is very essential for efficient and faster imaging of the environment using radars for both commercial and defensive purposes. Very often this is implemented in mechanical domain, which leads to numerous shortcomings like limited lifetime, electro-magnetic effects etc. To get continuous beam angle control, we use electro-optic effect. In the electro-optic waveguide approach,...
A race-track ring resonator with a 600 mum diameter and 25 GHz free spectral range is demonstrated by vertically integrating arsenic-trisulfide (As2S3) waveguides with Ti-diffused LiNbO3 waveguides. Measurements of the TM ring resonator response are presented.
