Abstract:

A reconfigurable optical interleaver/deinterleaver device combines/separates a pair of optical input signals from and/or to an optical WDM input signal. The interleaver device includes a spatial light modulator having a micro-mirror device with a two-dimensional array of micro-mirrors that flip between first and second positions in a “digital” fashion in response to a control signal provided by a controller in accordance with a switching algorithm and an input command. A pair of collimators, diffraction gratings and Fourier lens collectively collimate, separate and focus the optical input channels and optical add channels onto the array of micro-mirrors. Each optical channel is focused on a plurality of micro-mirrors of the micro-mirror device, which effectively pixelates the optical channels.

Abstract:

A chromatic dispersion compensation device selectively delays a respective portion of spectral sections of each respective optical channel of an optical WDM input signal to compensate each optical channel for dispersion compensation, and includes a spatial light modulator having a micromirror device with a two-dimensional array of micromirrors. The micromirrors tilt or flip between first and second positions in a “digital” fashion in response to a control signal provided by a controller in accordance with a switching algorithm and an input command. A collimator, diffraction gratings, and Fourier lens collectively collimate, disperse and focus the optical input channels onto the array of micromirrors. Each optical channel is focused onto micromirrors of the micromirror device, which effectively pixelates the optical channels. To compensate an optical channel for chromatic dispersion, a portion of the spectral sections of each channel is delayed a desired time period by tilting an array of mirrors (i. e.

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 “digital” 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:

An dynamic optical filter is provided to selectively attenuate or filter a wavelength band(s) of light (i. e. , optical channel(s)) or a group(s) of wavelength bands of an optical WDM input signal The optical filter is controllable or programmable to selectively provide a desired filter function. The optical filter includes a spatial light modulator which comprises an array of micromirrors that effectively forms a two-dimensional diffraction grating mounted in a retro-reflecting configuration. Each optical channel is dispersed separately or overlappingly onto the array of micro-mirrors along a spectral axis or direction such that each optical channel or group of optical channels are spread over a plurality of micromirrors to effectively pixelate each of the optical channels or input signal. Each channel or group of channels may be selectively attenuated by flipping or tilting a selected number of micromirrors to thereby deflect a portion of the incident radiation away from the return optical path. The micro-mirrors operate in a digital manner by flipping between a first and second position in response to a control signal provided by a controller in accordance with an attenuation algorithm and an input command The switching algorithm may provide a bit (or pixel) map or look-up table indicative of the state of each of the micro-mirrors of the array to selectively attenuate the input signal and provide a modified output signal at optical fiber.

US Classification:

359566, 359900, 385 37, 385147

Abstract:

A method for manufacturing a diffusion grating-based optical identification element is provided. The optical identification element includes a known fiber substrate, having a diffraction grating disposed therein the grating being indicative of a code when exposed to incident light. A large number of elements or microbeads all having the same identification codes can be manufactured by cutting the substrate transversely where the grating is located, thereby creating a plurality of elements, at least two of the elements having the grating therein along substantially the entire length of the elements. The elements may be manufactured in many different ways, including winding the fiber onto a basket, forming the gratings in the basket openings or bays, removing the fiber and cutting the fiber to form the elements 8. Each bay may have a set of elements with a unique set of codes therein.

Abstract:

A reconfigurable multifunctional optical device has an optical arrangement for receiving an optical signal, each having optical bands or channels, and a spatial light modulator for reflecting the at least one optical signal provided thereon. The optical arrangement features a free optics configuration with a light dispersion element for spreading each optical signal into one or more respective optical bands or channels for performing separate optical functions on each optical signal. The spatial light modulator includes a micro-mirror device with an array of micro-mirrors, and the respective optical bands or channels reflect off respective micro-mirrors. The free optics configuration includes a common set of optical components for performing each separate optical function on each optical signal. The separate optical functions reflect off separate non-overlapping areas on the spatial light modulator. The separate optical functions include optical switching, conditioning or monitoring functions.
