Abstract: An optical device may include a dispersion element. The optical device may include a reflective optic to reflect an optical beam with a fixed offset perpendicular to a dispersion direction of the dispersion element and with a negative offset in the dispersion direction of the dispersion element. The reflective optic may be aligned to the dispersion element to offset an optical beam with respect to the dispersion element and to cause the optical beam to pass through the dispersion element on a plurality of passes, offsetting the optical beam on each of the plurality of passes.

Abstract: A free-space MCS may include an input port to launch a beam of light, N output ports, a beam splitter to split the beam of light into N portions, and a deflector array including N deflectors aligned in an array direction. Each deflector may have an active region with a size in the array direction that matches a size in the array direction of a portion, of the N portions, incident thereon. The free-space MCS may include first beam shaping optics to form a first elliptical beam spot at the beam splitter with a major axis substantially perpendicular to the switching direction, and an angle-to-offset element to direct each of the N portions from the beam splitter to a different deflector of the N deflectors. Each of the N portions may have, at the deflector, a second elliptical beam spot with a major axis substantially parallel to the switching direction.

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: 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.
