Abstract:
1. A method of optically switching multiple wavelengths to and from a two-dimensional array of optical ports, comprising: controlling the single-axis angular position of rotating micromirror elements within a first and second micromirror array; receiving an optical beam containing multiple wavelengths from a two-dimensional array of optical ports; dispersing wavelength components of said optical beam which reflect from a wavelength dispersive element; reflecting said wavelength components from micromirror elements of the first micromirror array in a first plane toward the second micromirror array in a second plane; reflecting said wavelength components from micromirror elements in said second micromirror array in the second plane toward said first micromirror array; reflecting said wavelength components from micromirror elements in said first micromirror array toward said wavelength dispersive element; and directing an optical beam containing said wavelength components from said wavelength dispersive element to said two-dimensional array of optical ports.
