Abstract: The modulator includes a ring resonator having a phase modulator that tunes blocked wavelengths within phase modulator bandwidths. The blocked bands include blocked wavelengths at which the intensity of an output light signal is minimized. Each of the blocked bands is associated with the phase modulator bandwidth within which the blocked wavelength is tuned. A bandwidth shifting device is configured to shift a selection of wavelengths that falls within each of the phase modulator bandwidths. Electronics are configured to operate the bandwidth shifting device so as to shift the phase modulator bandwidths from a location where a first target wavelength falls within a first one of the phase modulator bandwidths to a location where a second target wavelength falls within a second one of the phase modulator bandwidths.

Abstract: An optical system includes a laser cavity on a base. The laser cavity generates a light signal in response to application of an electrical current to the laser cavity. The system includes first electronics that apply a target level of the electrical current to the laser cavity so as to cause the laser cavity to generate the light signal. The light signal experiences mode hops at electrical current levels that shift to higher current levels in response to increasing laser operation times. A first one of the mode hops occurs at a first current level and a second one of the mode hops occurs at a second current level that is higher than the first current level. The system also includes a phase shifter that interacts with the laser cavity so as to shift the mode hops to lower current levels than occur in the absence of the phase shifter.

Abstract: A wafer includes multiple optical devices. One of the devices includes a waveguide that terminates at a facet that is included in a testing port. Light is injected from a light source into the waveguide through the facet without being reflected between exiting from the light source and entering the facet. The devices are separated from the wafer after the light is injected into the waveguide.
