Abstract
Disclosed is an optical beam deflector. An optical beam deflector includes a substrate including a source region, an amplification region adjacent to the source region, a deflection region adjacent to the amplification region, and an antenna region adjacent to the deflection region, a waveguide layer provided on the substrate and extending from the source region to the antenna region, a lens layer selectively provided on the waveguide layer in the deflection region, and an upper clad layer on the lens layer and the waveguide layer.
