Abstract: A tunable multiport optical filter includes various types of arrays of optical ports. The tunable filter also includes a light dispersion element (e.g., a grating) and a reflective beam steering element (e.g., a tilting mirror). An optical signal exits an optical (input) port, is dispersed by the light dispersion element, reflects off the reflective beam steering element back to the light dispersion element, and on to another optical (output) port. The reflective beam steering element can be steered such that a wavelength portion of the dispersed optical signal can be coupled to the optical output port. For example, the input optical signal may be a wavelength division multiplexed signal carrying multiple channels on different wavelengths, and the tunable multiport optical filter directs one of the channels to the output optical port. Additionally, the tunable filter may be incorporated into a device act as a wavelength reference.

Abstract: A micromirror for use in an optical apparatus may comprise a reflective portion, configured to be rotatable about a switching axis and an attenuation axis that is different from the switching axis. The reflective portion may include an edge that is substantially parallel to the attenuation axis. The edge may include one or more edge features that protrude above a plane of the micromirror surface and/or are submerged below the plane of the micromirror surface, and/or have an edge shape that deviates from a straight line. Alternatively, an array of micromirrors may have mirrors characterized by sawtooth features disposed along edges that are substantially parallel to the attenuation axis.

Abstract: A multicast optical switch includes a free-space optical assembly of discrete splitters, cylindrical optics, and a linear array of reflective switching devices, such as microelectromechanical systems (MEMS) mirrors, to provide low-loss, high-performance multicast switching in a compact configuration. The assembly of optical splitters may include multiple planar lightwave circuit splitters or a multi-reflection beam splitter that includes a linear array of partially reflecting mirrors, each of a different reflectivity.

Abstract: Optical switches can include collimator elements that accommodate two or more optical ports. This increases the number of ports the switch can accommodate without having to increase the size of other optical components within the switch. Separate deflectors can be used to accommodate optical signals from two different groups of ports. In some embodiments cross-coupling of signals between the two groups can be accomplished through use of re-direction optics.
