Abstract: A reconfigurable optical blocking filter deletes a desired optical channel(s) from an optical WDM input signal, and includes a spatial light modulator having a micro-mirror device with a two-dimensional array of micro-mirrors that tilt between first and second positions in a nulldigitalnull fashion in response to a control signal provided by a controller in accordance with a switching algorithm and an input command. A collimators, diffraction grating, and Fourier lens, collectively collimate, separate and focus the optical input channels onto the array of micro-mirrors. The optical channel is focused on the micro-mirrors onto a plurality of micro-mirrors of the micro-mirror device, which effectively pixelates the optical channels. To delete an input channel of the optical input signal, micro-mirrors associated with each desired input channel are tilted to reflect the desired input channel away from the return path.

Abstract: A reconfigurable optical device capable of filtering, multiplexing, and spectrometry, among other functions. The device has an array of micromirrors disposed under a floating reflector that is partially reflecting. The floating reflector is spaced apart from the micromirrors a certain distance. The micromirrors are each capable of independent vertical motion, and, optionally, tilting motion. In use, light is projected at an oblique angle into the space between the micromirrors. Each reflection from the floating reflector produces an emergent beam from the floating reflector. The emergent light beams are combined with a lens. As a direct result of this structure, different wavelengths are focused to different points in the focal plane of the lens. The focal point positions of the different wavelengths can be moved by manipulating the micromirrors. This allows for reconfigurable filtering, spectrometry, and multiplexing, among other applications.

Abstract: An optical filter for generating a filter output signal from a filter input signal, the filter output signal consisting of light from the filter input signal in a predetermined bandwidth. The filter includes a grating, a first optical assembly and an optical signal path. A portion of the input signal traverses the optical signal path such that it is diffracted from the grating to form a first intermediate beam that is input to the first optical assembly, which generates a second intermediate beam therefrom. The second intermediate beam is directed back to the grating and is diffracted by the grating, a portion of the diffracted second intermediate beam forming a portion of the filter output signal. The second intermediate beam is the inverted image of the first intermediate beam, and hence, the second reflection from the grating compensates for the time dispersion introduced by the first reflection from the grating.

Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin2(m&thgr;+p&pgr;/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by correspond filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.
