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: A wavelength selective switch (WSS) may include a first port array including input ports, each to launch a respective beam of light, and a dispersive element to separate, in a lateral direction, a beam of light, launched by one of the input ports, into dispersed wavelength channel sub-beams. The WSS may include a switching array to direct the dispersed wavelength channel sub-beams, at respective angles in a vertical direction. The dispersive element may converge groups of dispersed wavelength channel sub-beams in the lateral direction to form wavelength channel sub-beams. The WSS may include a splitting element to split, in the lateral direction, a wavelength channel sub-beam, of the wavelength channel sub-beams, into split wavelength channel sub-beams. The WSS may include switching elements to direct the split wavelength channel sub-beams at respective angles in the vertical direction, and output ports associated with the switching elements.

Abstract: A first configuration of an optical node may include a set of degrees, each including an inbound wavelength selective switch (WSS) and an outbound WSS. The first configuration may include a first degree expansion including a first inbound expansion WSS and a first outbound expansion WSS. An expansion input of the first inbound expansion WSS may connect to an expansion output of a second outbound expansion WSS included in a second degree expansion of a second configuration of the optical node. An expansion output of the first outbound expansion WSS may connect to an expansion input of a second inbound expansion WSS included in the second degree expansion of the second configuration. A signal input to an inbound WSS of a given one of the set of degrees may be routed, via the first degree expansion and the second degree expansion, to any drop port included in the second configuration.

Abstract: An optical node may include D (D≥2) input ports, D output ports, and D degrees. Each degree may include an inbound M×N (M≥D, N≥2D) WSS and an outbound M×N WSS. Each inbound M×N WSS may include an input connected to one of the D input ports; inputs connected to outputs of inbound M×N WSSs of the other degrees; outputs connected to inputs of outbound M×N WSSs of the other degrees; outputs connected to inputs of inbound M×N WSSs of the other degrees; and a local drop port. Each outbound M×N WSS may include an output connected to one of the D input ports; outputs connected to inputs of outbound M×N WSSs of the other degrees; inputs connected to outputs of inbound M×N WSSs of the other degrees; inputs connected to outputs of outbound M×N WSSs of the other degrees; and a local add port.

Abstract: An optical cross-connect including two deflector arrays optically separated by an angle-to-offset (ATO) element, wherein each deflector array includes a plurality of deflectors aligned in an array direction, each deflector array having a switching direction substantially perpendicular to the corresponding array direction, the array direction of the two deflector arrays being substantially perpendicular. Beam shaping optics convert light transmitted towards the first deflector array to have an elliptical cross-section at the first deflector array, thus providing a relatively simple and compact optical cross-connect.

Abstract: A multicast optical switch uses a diffractive bulk optical element, which splits at least one input optical beam into sub-beams, which freely propagate in a medium towards an array of directors, such as MEMS switches, for directing the sub-beams to output ports. Freely propagating optical beams can cross each other without introducing mutual optical loss. The amount of crosstalk is limited by scattering in the optical medium, which can be made virtually non-existent. Therefore, the number of the crossover connections, and consequently the number of inputs and outputs of a multicast optical switch, can be increased substantially without a loss or a crosstalk penalty.

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.
