Abstract: Modular WSS (wavelength selective switch) designs are provided that allow a WSS to be built out for a first set of wavelengths, with the capacity for later expansion to handle a second set of wavelengths with minimal impact on the operation of the system for the first set of wavelengths. An optical signal separator separates each incoming signal into the two bands, and at each output, the bands are then re-combined. In between, wavelength selective switching is performed separately for each of the two bands, or initially only for one of the bands, with later upgradability to switch the second band.

Abstract: A wavelength cross connect is provided in which wavelength channels are individually switchable from one of a first set of ports to one of a second set of ports. Add and drop capability is provided on the sets of ports. Some embodiments feature a single row of ports, while others feature two dimensional arrays of ports. Some embodiments employ one dispersive element per port, and others employ one dispersive element per row of ports. Embodiments featuring transmissive and non-transmissive switching elements a re provided.

Abstract: An apparatus, system, and method for all-optical wavelength add-drop switchi ng are provided. A number of optical ports, including at least one input port a nd at least one output port, are each optically coupled to a respective dispersive element. When a multichannel optical signal is input through an input port, an optical beam of each channel emerges from the dispersive element at an angle depending upon its wavelength. The beams emerging from t he dispersive element pass through a bulk optical element which redirects each beam toward a respective one of a number of routing or switching elements, each of which has been set to redirect the respective beam through the bulk optical element towards a selected dispersive element coupled to a selected output port.

Abstract: A wavelength selective switch is realized by combining a quantized dispersion element and an array of switching means. The quantized dispersion element enables to concentrate all the wavelengths within predetermined wavelength bands onto the same location in the switching array. With this arrangement, a low fill factor switching array can be used while maintaining good flat-top spectral performance with no spectral dips and improving alignment tolerances.

Abstract: The invention provides a micro-electro-mechanical-system (MEMS) mirror device, comprising: a mirror having a 2-dimensional rotational articulated hinge at a first end, and having a 1-dimensional rotational articulated hinge at a second end opposite the first end; a movable cantilever connected to the mirror through the 1-dimensional rotational articulated hinge; a support structure connected to the mirror through the 2-dimensional rotational articulated hinge and connected to the movable cantilever; whereby movement of said movable cantilever causes rotation of the mirror in a first axis of rotation, and the mirror is also rotatable about a second torsional axis of rotation perpendicular to said first axis of rotation.
