    Abstract: An example optical system having an optical supply sub-system for supplying light to a photonic integrated circuit is presented. The optical supply sub-system includes a primary light source, an auxiliary light source, a first optical coupler, and a second optical coupler. The first optical coupler includes a first metal-oxide-semiconductor capacitor microring resonator (MOSCAP MRR) and the first optical coupler includes a second MOSCAP MRR. The first optical coupler is coupled to the primary light source and the photonic integrated circuit to control the propagation of the primary light to the photonic integrated circuit. The auxiliary light source may be configured to generate an auxiliary light when the primary light source malfunctions and the first MOSCAP MRR and the second MOSCAP MRR are controlled to control propagation of the auxiliary light from the auxiliary light source to the photonic integrated circuit.

    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: Examples herein relate to optoelectronic systems or modules. In particular, implementations herein relate to an optoelectronic module or system that includes a substrate having opposing first and second sides and an optoelectronic component having opposing first and second sides flip chip assembled to the substrate. The optoelectronic component is configured to emit at least one optical signal to the substrate, receive at least one optical signal from the substrate, or both. The optoelectronic system further includes an underfill exclusion structure configured to prevent underfill material dispensed between the optoelectronic component and the substrate from flowing into an optical area or path of the at least one optical signal transmitted between the optoelectronic component and the substrate. The underfill exclusion structure is spaced apart from at least one of the optoelectronic component or the substrate.

    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.
