Abstract
Examples described herein relate to a ring resonator. The ring resonator may include an annular waveguide having a waveguide base and a waveguide core narrower than the waveguide base. Further, the ring resonator may include an outer contact region comprising a first-type doping and disposed annularly and at least partially surrounding an outer annular surface of the waveguide base. Furthermore, the ring resonator may include an inner contact region comprising a second-type doping and disposed annularly contacting an inner annular surface of the waveguide base. Moreover, the ring resonator may include an annular detector region disposed annularly at a distance from and covering at least a portion of a surface of the waveguide core and contacting the outer contact region.
