First Claim
1. An optical system comprising two or more optical switches for switching one or more optical signals, the signals comprising one or more optical wavelengths, each optical wavelength constituting a work piece, each said switch comprising:
- a plurality of input fiber ports, each said input fiber port serving as an external interface for introducing the at least one input optical signal into a first optical switch of said two or more optical switches;

at least one shared arrayed switching element for receiving at least one wavelength from said plurality of input fiber ports and for switching the at least one wavelength from one of said plurality of input fiber ports to one of said plurality of output fiber ports according to a state of at least one switch of said at least one shared arrayed switching element;
at least one shared wavelength dispersive element for spatially separating at least one first wavelength of the input optical signal from at least one other wavelength of the input optical signal and for recombining at least one first wavelength of the output optical signal with at least one other wavelength of the output optical signal;
at least one shared arrayed steering element for steering the at least one wavelength from at least one of said plurality of input fiber ports onto said at least one shared arrayed switching element, and for steering the at least one wavelength from said at least one shared arrayed switching element to at least one of said plurality of output fiber ports;
one or more shared optical elements, wherein each said optical element focuses the optical signals of said at least one of said plurality of input fiber ports and said at least one of said plurality of output fiber ports; and

Abstract
An optical comprising two or more mixed optical switches co-packaged together comprising discrete sets of fiber ports, each configured as N×1 optical switch or 1×N optical switch, wherein λn from said input fiber ports is focused on λn mirror via the use of shared free space optics elements, wherein beam steering elements steers λn from any point in the optical path to any other point; and discrete arrays of micro electromechanical system (MEMS) mirrors in a shared array, wherein first array of mirrors is utilized to select and switch selected wavelengths from input fiber ports to output fiber port of the same set, wherein second array of mirrors using and sharing the same shared optics is utilized to select and switch selected wavelengths between input and output ports belonging to another set; and wherein output fiber ports from one set can be coupled to input ports of other sets.
