Abstract: Implementations disclosed herein provide semiconductor resonator based optical multiplexers that achieve enhanced bandwidth range of light emitted therefrom. The present disclosure integrates silicon devices into resonator structures, such as micro-ring resonators, that couples a side mode with a lasing mode and resonantly amplifies coupled light to output light having an enhanced bandwidth with respect to the lasing mode. In some examples, the optical multiplexers disclosed herein include a bus waveguide; a first resonator structure optically coupled to the bus waveguide and comprising an optical amplification mechanism that generates light and a single mode filter to force the generated light into single-mode operation; and a second resonator structure optically coupled to the first resonator structure and comprising a phase-tuning mechanism. The phase-tuning mechanism can be controlled to detune phase of light in the second resonator relative to the light in the first resonator.

Abstract: Resonant cavity photodetector structures which integrate photodetection and filtering capabilities is described. A resonant cavity photodetector structure generally can comprise a region including a resonator, and an absorption region that can be integrated into a cavity of the resonator. The resonator can perform filtering that is suitable for high-bandwidth optical communications, such as Dense Wavelength Multiplexing (DWDM). In some cases, the resonator is a microring resonator. An absorption region can include a photodiode which performs optical energy detection acting as a photodetector, such as an avalanche photodiode (APD) wherein the photodiode. A coupling distance between the resonator region and the absorption region can be controlled, which allows control of a coupling strength between an optical mode of the resonator and the absorption region such that a quality factor (Q-factor) can be tuned. Thus, by adjusting the Q-factor, the resonant cavity photodetector structure can be tuned to achieve a desirable performance.
