Abstract: The specification describes optical performance monitors which are simplified by coupling single tunable optical filters to multiple channels being monitored. Optical measurements for more than one channel may be made simultaneously. The optical system architecture is preferably an optical performance monitor for a WDM system. In a system designed according to the invention n channels may be monitored using n photodetectors, n optical splitters, but only n/2 tunable optical filters. Additional system simplification may be obtained using optical switching elements coupled to the optical splitters.

Abstract: An optical performance monitoring system includes a four-port tap coupling a tunable optical filter to a light detector. The four-port tap is configured as an optical tap and an optical splitter combined into a single optical element, where the optical tap directs a portion of an optical signal from an optical fiber to the tunable optical filter, and the optical splitter directs the optical signal from the tunable optical filter to the light detector. The optical performance monitoring system may employ tunable optical filters as a double-duty tunable filter or a double-pass tunable filter. As a double-duty tunable filter, optical signals to be monitored are passed through the tunable filter in opposite directions. As a double-pass tunable filter, a reflecting element is arranged on the output side of the tunable filter so that a filtered optical signal can be fed back into the tunable filter.

Abstract: An optical device for a wavelength division multiplexing system has a telecentric lens system and a signal-processing optical element, where the signal-processing optical element performs switching, attenuation, or other optical signal processing for the optical device. The telecentric lens system acts as a self-compensating optical system to minimize sensitivity of the optical device to unwanted displacement of an input image from the optical axis of the optical device. The optical device may include multiple telecentric lens systems, in which case the optical device is also less sensitive to precise alignment between the telecentric lens systems.

Abstract: An optical switch for performing high extinction ratio switching of an optical signal includes a beam polarizing element and one or more optical elements. The optical elements are configured to direct an optical signal along a first or second optical path based on the polarization state of the optical signal as it passes through the optical elements. The optical switch performs high extinction ratio switching of the optical signal by preventing unwanted optical energy from entering an output port by using an absorptive or reflective optical element or by directing the unwanted optical energy along a different optical path.

Abstract: A fiber lens assembly is configured to optically couple an optical fiber to a signal processing device having free-space optical elements. The fiber lens assembly includes a diverging lens having a focal length that may be around 2 to 6 times the diameter of the optical fiber core. Sensitivity of the fiber lens assembly to angular misalignment and positional displacement is reduced by coupling the optical fiber to the signal processing device using a diverging lens rather than a collimating lens, and by configuring the diverging lens with a suitable focal length.

Abstract: The present invention provides an improved gain slope equalizer which provides variable optical attenuation. The gain slope equalizer includes a transmission diffraction grating with a first side and a second side; a first lens optically coupled to the second side of the transmission diffraction grating; and at least one reflective surface optically coupled to the first lens at a side opposite to the transmission diffraction grating. The gain slope equalizer in accordance with the present invention can also be used with a Virtually Imaged Phased Array (VIPA) to provide a chromatic dispersion slope and chromatic dispersion compensation as well as variable optical attenuation. The present invention provides the heretofore unavailable capability of simultaneous tunable gain slope equalization and chromatic dispersion compensation utilizing a single apparatus.

Abstract: The present invention provides a dispersion compensator which utilizes a Virtually Imaged Phased Array (VIPA), gratings, and birefringent wedges to moderate chromatic dispersion, dispersion slope and polarization mode dispersion, and a method and system for testing such a dispersion compensator. The dispersion compensator in accordance with the present invention propagates the composite optical signal in a forward direction; separates the wavelengths in the band of wavelengths in each of the plurality of channels, where each of the wavelengths in the band is spatially distinguishable from the other wavelengths in the band; spatially separates each band of wavelengths in the plurality of channels; spatially separates each wavelength of each separated band of wavelengths into a plurality of polarized rays; and reflects the plurality of polarized rays toward a return direction, where dispersion is added to the reflected plurality of polarized rays such that the unwanted chromatic dispersion, dispersion slope, and PMD are compensated. The dispersion compensator provides simultaneous tunable compensation of these various dispersions utilizing a single apparatus. A system which utilizes the compensator is thus cost effective to manufacture. Systems may be provides which determines the operating and performance parameters for the compensator, and measures the spectrum outputted by the compensator.

Abstract: A system and method for treating tailings from a bitumen froth treatment process such as TSRU tailings. The tailings are dewatered to at least 50 wt percent solids content, and then combusted to convert kaolin in the tailings into metakaolin. Calcined fines and heavy minerals may be recovered from the combustion products, namely from the flue gas or bottom ash or both. A trafficable deposit may be formed from the ash when mixed with tailings, such as mature fine tailings (MFT).
