Abstract: A device may include a first photodetector to generate a first current based on an optical power of an optical beam. The device may include a beam splitter to split a portion of the optical beam into a first beam and a second beam. The device may include a wavelength filter to filter the first beam and the second beam. The wavelength filter may filter the second beam differently than the first beam based on a difference between an optical path length of the first beam and an optical path length of the second beam through the wavelength filter. The device may include second and third photodetectors to respectively receive, after the wavelength filter, the first beam and the second beam and to generate respective second currents.

Abstract: A wavelength selective switch (WSS) may include a front-end unit that includes an input few-mode fiber (FMF) providing an input optical signal including multiple wavelengths. The multiple wavelengths may each have N modes. The front-end unit may include two or more output few-mode fibers (FMFs), and a side that has a 1×N port for each of the input FMF and the two or more output FMFs. Each of the 1×N ports may be single mode in a wavelength dispersion dimension and N-mode in a switching dimension. The WSS may include a switching element to receive the input optical signal from the front-end unit, switch each of the multiple wavelengths of the input optical signal to form one or more output optical signals, and direct each of the one or more output optical signals to a corresponding 1×N port of the front-end unit.

Abstract: A zoned waveplate has a series of transversely stacked birefringent zones alternating with non-birefringent zones. The birefringent and non-birefringent zones are integrally formed upon an AR-coated face of a single substrate by patterning the AR coated face of the substrate with zero-order sub-wavelength form-birefringent gratings configured to have a target retardance. The layer structure of the AR coating is designed to provide the target birefringence in the patterned zones and the reflection suppression.

Abstract: The number of wavelength selective switch (WSS) units in a WSS device can be doubled by using polarization properties of optical beams propagating through the WSS device. Beams from different WSS units are orthogonally polarized at the front end, propagated through collimator, wavelength dispersing element, and a focusing element, and impinge on a polarizing beamsplitter, which directs sub-beams at different polarizations to different directing elements of a director array. A polarization diversity configuration at the back end can be used to reduce polarization dependent loss.

Abstract: An optical device may include a laser component to emit a source beam and an optical component to split the source beam to generate a first beam and a second beam. The optical device may include a multiplexing component to multiplex the first beam and the second beam to form a first multiplexed beam, an optical system to receive the first multiplexed beam and demultiplex the first beam and the second beam, and a scanning component to scan a field of view with the first beam and the second beam and receive the first beam and the second beam reflected from the field of view. The optical system may multiplex the first beam and the second beam reflected from the field of view to form a second multiplexed beam, and a demultiplexing component may demultiplex the first beam and the second beam reflected from the field of view.

Abstract: An optical device may include a monolithic beam steering engine. The device may include a twin M×N wavelength selective switch (WSS) including a first M×N WSS and a second M×N WSS. The first M×N WSS may include a first panel section of the monolithic beam steering engine to perform first beam steering of first beams, wherein the first beam steering is add/drop port beam steering; and a second panel section of the monolithic beam steering engine to perform second beam steering of second beams, wherein the second beam steering is common port beam steering. The first M×N WSS may include a first optical element aligned to the monolithic beam steering engine to direct one of the first beams or the second beams relative to the other of the first beams or the second beams, such that the first beams are directed in a different direction from the second beams.
