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: Pluggable optical transceiver modules are described herein that are specifically configured to preclude use of fiber jumpers inside of the module. The pluggable optical transceiver modules include an on-board application-specific integrated circuit (ASIC), optical transceiver, and an optical socket allowing a fiber to connect to the optical transceiver. Pluggable optical transceiver modules implement an opto-mechanical interface between an external fiber cable (attached to the pluggable optical transceiver module) and the optical transceiver in manner that does not require the fiber jumper, while ensuring tight alignment tolerances. In some embodiments, optical transceiver modules are designed to achieve a direct opt-mechanical coupling between the external fiber cable and on-board opto-electrical components (e.g., optical transceiver). For example, an adaptor is distinctly designed, directly connecting an external cable to the optical socket (eliminating the use of fiber jumper and faceplate connector in the module). In some embodiments, a rigid body opto-mechanical interface is used.

Abstract: A silicon interposer may include an on-chip DC blocking capacitor, comprising: a first electrical connection to couple to a supply voltage and to cathodes of a plurality of photodiodes formed in a two-dimensional photodiode array on a first substrate, and a second electrical connection to couple to ground and to ground inputs of a plurality of transimpedance amplifiers on a second substrate; wherein the on-chip DC blocking capacitor is configured to be shared among a plurality of receiver circuits comprising the plurality of photodiodes and the plurality of transimpedance amplifiers; and wherein the silicon interposer comprises a substrate separate from the first substrate and the second substrate.
