Abstract
An optical system may include a substrate that includes an etched region and a laser-induced breakage region. The optical system may further include an optical waveguide disposed on the substrate. The optical system may further include an optical device coupled to the optical waveguide within the etched region. The laser-induced breakage region may produce a predetermined coupling gap between the optical waveguide and the optical device.
