Abstract
An optical coupling device is described herein. The optical coupling device comprises a first waveguide and a second waveguide that are formed on a common substrate, and a resonator that is positioned out of plane with the two waveguides. The resonator and waveguides are positioned such that light traveling in each of the waveguides evanescently couples to the resonator but not to the other of the waveguides. The optical coupling device can be used in connection with improving linewidth of a laser source for a lidar sensor. In another example, the optical coupling device can be used in connection with wavelength division multiplexing.
