    Abstract: Implementations disclosed herein provide for improving phase tuning efficiency of optical devices, such as a hybrid metal-on-semiconductor capacitor (MOSCAP) III-V/Si micro-ring laser. The present disclosure integrates silicon devices into a waveguide structural of the optical devices disclosed herein, for example, a waveguide resistor heater, a waveguide PIN diode, and waveguide PN diode. In some examples, the optical devices is a MOSCAP formed by a dielectric layer between two semiconductor layers, which provides for small phase tuning via plasma dispersion and/or carrier dispersion effect will occur depending on bias polarity. The plasma dispersion and/or carrier dispersion effect is enhanced according to implementations disclosed herein by heat, carrier injection, and/or additional plasma dispersion based on the silicon devices disclosed integrated into the waveguide.

    Abstract: Examples herein relate to optical systems. In particular, implementations herein relate to an optical system including an optical transmitter configured to transmit optical signals. The optical transmitter includes a first optical source coupled to an input waveguide and configured to emit light having different wavelengths through the input waveguide. The optical transmitter includes a Mach-Zehnder interferometer that includes a first arm and a second arm. The MZI further includes a first optical coupler configured to couple the emitted light from the input waveguide to the first and second arms and an array of two or more second optical sources coupled to the first arm. Each of the two or more second optical sources are configured to be injection locked to a different respective wavelength of the emitted light transmitted from the first optical source. The MZI further includes a second optical coupler configured to combine the emitted light from the first and second arms after propagating therethrough.

    Abstract: Examples herein relate to optical systems. In particular, implementations herein relate to an optical system including an optical transmitter configured to transmit optical signals. The optical transmitter includes a first optical source and a second optical source coupled to the first optical source and injection seeded by the first optical source. The optical transmitter further includes an output coupler, the second optical source coupled to the optical coupler via an output waveguide and configured to emit light having multiple different wavelengths through the output waveguide. In some implementations, the second optical source is self-injection seeded.

    Abstract: An example system for multi-wavelength optical signal splitting is disclosed. The example disclosed herein comprises a first splitter, a second splitter, and a modulator. The system receives a multi-wavelength optical signal and an electrical signal, wherein the multi-wavelength optical signal comprises a plurality of optical wavelengths and has a power level. The first splitter is to split the plurality of optical wavelengths into a plurality of optical wavelength groups. The second splitter is to split the multi-wavelength optical signal or the plurality of optical wavelength groups into a plurality of lower power signal groups. The modulator is to encode the electrical signal into the plurality of optical wavelength groups, the plurality of lower power signal groups, or a combination thereof.
