Abstract: Systems and methods for modifying, switching, rearranging or otherwise controlling the individual wavelength components of DWDM optical signals are described, which employ compact refolding and reshaping of these dimensionally patterned beams within a confined volume. The wavelength components of the beam are diffractively dispersed with high diffraction efficiency, and then reversely converged to beam waists incident on different ones of an array of control elements such as liquid crystal cells, MEMs and other spatial light modulators, or fixed distributed patterns. With reflective control elements the wavelength components may be reversely refolded along reciprocal paths with rediffraction, to form a reconstituted and revised DWDM output signal. If the control elements transmit at least one of the wavelength components, a separate, adjacent three dimensional beam refolding path, with rediffraction, is used to feed recombined signals to a separate output. High diffraction efficiency and minimal optical aberrations are achieved by employing a diffraction grating and opposed Mangin mirror system as the principal elements for beam refolding. The approach is useful in systems servicing narrow channel separations, and in a wide variety of applications including channel equalization, interleaving, channel blocking, and channel grouping.

Abstract: A multi-channel wavelength monitor is described that includes a dispersive element that is positioned in an optical path of an incident optical beam having a plurality of wavelengths. The dispersive element disperses the optical beam into a plurality of optical beams that simultaneously propagate in a plurality of optical paths, where each of the plurality of optical beams has one of the plurality of wavelengths. An optical filter is positioned to intercept each of the plurality of optical paths at a plurality of locations. The optical filter substantially passes a respective one of the plurality of optical beams at a respective one of the plurality of locations and substantially blocks the other optical beams. A plurality of optical detectors is positioned adjacent to the optical filter in a direction of propagation of the plurality of optical beams. A respective one of the plurality of optical detectors is positioned in a respective one of the plurality of optical paths. Each of the plurality of detectors generates an electrical signal that is proportional to an intensity of a respective one of the plurality of optical beams.

Abstract: Lighting systems comprising a spectrum former upstream from a reflective pixelated spatial light modulator (reflective SLM), the SLM reflecting substantially all of the light in the spectrum into at least two different light paths, that do not reflect back to the light source or the spectrum former. At least one of the light paths acts as a projection light path and transmits desired light out of the lighting system. The lighting systems provide virtually any desired color(s) and intensity(s) of light, and avoid overheating problems by deflecting unwanted light and other electromagnetic radiation out of the system or to a heat management system. The systems can be part of another system, a luminaire, or any other suitable light source. The systems can provide virtually any desired light, from the light seen at the break of morning to specialized light for treating cancer or psoriasis, and may change color and intensity at speeds that are perceptually instantaneous.

Abstract: A compact, grating spectrometer (1A) particularly adapted for visual observation of the sun's spectrum, from the Calcium K line to the Fraunhofer B line, at very high dispersion. The numerical aperture of the spectrometer's collimating mirror is intentionally mismatched to the numerical aperture of the spectrometer's light-input device in order to exploit, by means of the exceedingly narrow width of the spectrometer's entrance slit (110), the high degree of coherence of the central region of the Airy disk formed by the light-input device. The resulting Fraunhofer diffraction illuminates totally, or nearly totally, the collimating mirror throughout the K-B interval. The human eye's dynamic range is compensated to maintain resolution at the lowest, light levels of the K-B interval. UV spill is suppressed. Both input-optics and slit are shielded against differential heating.

Abstract: An optical communication channel switch includes an aberration corrected spectrometer adapted for receiving plural channels of communication in a one dimensional array of sites where each site corresponds to a source, and a channel selector for selectively switching channels. After receiving the plural channels, the aberration corrected spectrometer provides the channels in a two dimensional array in which channels are distributed in rows (or columns) of similar frequency and different sources and in columns (or rows) of differing frequency and common sources. The channel selector selectively switches channels among sites in the two dimensional array and provides a single dimensional reconfigured array of frequency separated channels that is combined into the two dimensional array. Another aberration corrected spectrometer receives the selectively switched two dimensional array and combines the channels into a single dimensional array of sites having one or more frequency separated channels.
