摘要： Systems, methods, devices, and apparatuses generate a fully integrated broadband high power frequency combs, based on a multimode gain chip. Embodiments can generate a frequency comb spanning over ˜150 nm and include self-injection locking of a multimode chip-based gain, which can allow access to high pump power while maintaining single mode operation. The integrated frequency comb systems and methods can comprise a multimode gain chip, a ring resonator in optical communication with a waveguide and, and an integrated heater in thermal communication with the ring resonator. Embodiments can be configured to receive multimode gain input and effect a single-mode ring feedback to determine a target mode. A temperature of the ring resonator can be optionally adjusted to modulate the ring feedback, and the ring feedback can be applied to the multimode gain input to generate an output frequency comb that includes the target mode.

摘要： A probe structure includes a monolithically integrated waveguide and lens. The probe is based on SU-8 as a guiding material. A waveguide mold is defined using wet etching of silicon using a silicon dioxide mask patterned with 45° angle with respect to the silicon substrate edge and an aluminum layer acting as a mirror is deposited on the silicon substrate. A lens mold is made using isotropic etching of the fused silica substrate and then aligned to the silicon substrate. A waveguide polymer such as SU-8 2025 is flowed into the waveguide mask+lens mold (both on the same substrate) by decreasing its viscosity and using capillary forces via careful temperature control of the substrate.

摘要： Methods, systems, and devices are described for electro-optic tuning. An example device may comprise a first layer comprising a transition metal di-chalcogenide material, a second layer comprising a conductive material, and a third layer comprising a dielectric material. The third layer may be disposed at least partially between the first layer and the second layer. An electrical potential difference applied between the first layer and the second layer may cause a tunable refractive index change in the first layer.

摘要： Methods and systems are described for modulating optical signals. An example method may comprise supplying, via a waveguide, an optical signal to a resonator optically coupled to the waveguide. The method may comprise modulating a phase of the optical signal based on at least one layer comprising an electro-optic material having an electro-refractive property and an electro-absorptive property. The modulating of the phase may be based on using the at least one layer to tune a coupling of the waveguide and the resonator between being under-coupled and being over-coupled. The method may comprise outputting, via the waveguide, the modulated optical signal.
