Abstract: In one example, a device includes a bus waveguide to carry a light of a carrier wavelength, a first ring waveguide with a first modulator, a first heater to adjust a resonance wavelength of the first ring waveguide, and a second ring waveguide with a second modulator. The first ring waveguide and the second ring waveguide are coupled to the bus waveguide and are to modulate the light of the carrier wavelength to impart one of at least four optical power levels to the light. In another example, a device includes, a bus waveguide, a first ring waveguide with a first modulator, and a second ring waveguide with a second modulator. The first ring waveguide and the second ring waveguide are coupled to the bus waveguide and are to modulate a light of a carrier wavelength to impart one of at least four optical power levels to the light.

Abstract: An example system includes an optical modulator and a multiplexing controller. The modulator includes a data bus for receiving at least one data signal, a plurality of multiplexers and a plurality of modulating segments. Each multiplexer is coupled to the data bus to receive at least one data signal and to output a multiplexed signal. Each modulating segment may receive the multiplexed signal from one of the plurality of multiplexers and modulate the multiplexed signal using an optical input. The multiplexing controller may be in communication with the plurality of multiplexers and may configure each of the plurality of multiplexers in accordance with a selected modulation type.

Abstract: In example implementations, a method executed by a processor is provided. The method receives a simulated photonic data input based on a theoretical photonic design that meets a target specification. A complementary metal-oxide semiconductor (CMOS) circuit design is designed based on the simulated photonic data input using a pre-layout simulation. An experimental photonic data input based on a fabricated photonics device that meets the target specification is received. The CMOS circuit is designed based on the experimental photonic data input using a post-layout simulation. A physical circuit CMOS circuit design and a layout that includes detailed physical dimensions associated with the physical CMOS circuit design that is based on the pre-layout and the post-layout are transmitted to a CMOS foundry.

Abstract: A circuit includes a startup circuit to provide a charging signal to initiate startup of a reference circuit. The startup circuit includes a detector circuit having a detector current path control, a level shifter having a level shifter current path control, and a charger circuit having a charger current path control. Each of the detector current path control, the level shifter current path control, and the charger circuit current path control enable current flow in the startup circuit when the charger turn-on signal is in the on-state and disable the current flow in the startup circuit when the charger turn-on signal is in the off state.
