Abstract: A method of sensing a process utilizing a sensing apparatus consisting of more than one diode laser having select lasing frequencies, a multiplexer optically coupled to the outputs of the diode lasers with the multiplexer being further optically coupled to a pitch side optical fiber. Multiplexed laser light is transmitted through the pitch side optical fiber to a pitch optic operatively associated with a process chamber which may be a combustion chamber or the boiler of a coal or gas fired power plant. The pitch optic is oriented to project multiplexed laser output through the process chamber. Also operatively oriented with the process chamber is a catch optic in optical communication with the pitch optic to receive the multiplexed laser output projected through the process chamber. The catch optic is optically coupled to an optical fiber which transmits the multiplexed laser output to a demultiplexer. The demultiplexer demultiplexes the laser light and optically couples the select lasing frequencies of light to a detector with the detector being sensitive to one of the select lasing frequencies.

Abstract: A method of absorption spectroscopy including obtaining absorption data at multiple wavelengths along more than one line-of-sight path through a quantity of gas of interest. The method further includes identifying more than one temperature and gas species concentration bin along the multiple line-of-sight paths and creating a map of temperature and gas species concentration. The map thus created will have at least two-dimensional information derived from select temperature and gas species concentration bins identified along more than one line-of-sight path. Apparatus for implementing the above method is also disclosed.

Abstract: A (de)multiplexer for use in optical communications systems for multiplexing and demultiplexing an optical signal consisting of optical channel(s) of different wavelength(s) includes a multiplex optical waveguide propagating a plurality of optical channels and a plurality of single channel optical waveguides, each propagating a single channel. Each of the waveguides has a receiving/transmitting end. A diffraction grating is optically coupled between the multiplex optical waveguide and the single channel optical waveguides for diffracting an optical signal between the receiving/transmitting end of the multiplex optical waveguide and the receiving/transmitting end of the single channel optical waveguide. The grooves of the diffraction have spacing which varies according to an algorithm such that a portion of the optical signal diffracted by each groove is offset in a direction of dispersion relative to the portions of the optical signal diffracted by the other surfaces to broaden the transmission band at the receiving/transmitting ends of the single channel and multiplex optical waveguides. A method for fabricating a grating as described above includes etching grooves having spacing which varies according to the algorithm such that a portion of the optical signal diffracted by each surface is offset in a direction of dispersion relative to portions of the optical signal diffracted by each other surface.

Abstract: A reconfigurable add/drop multiplexer (100, 150) for use in an optical communications network includes an input optical waveguide (118, 162) propagating a multi-channel optical signal and a receiver optical waveguide (120, 170) optically aligned with the input waveguide. A transmission filter (106, 164) is in optical communication between the input optical waveguide and the receiver optical waveguide (120, 170) with the transmission filter being tunable to drop a select channel to the receiver optical waveguide (120, 170) and to reflect the remaining channels of the multi-channel optical signal. A retransmission waveguide (118, 162) is in optical communication with the transmission filter to receive the reflected remaining channels. A second receiver waveguide (130, 174) is in optical communication with the receiver waveguide (120, 170). A selectively reflective apparatus (108, 168) is in optical communication between the receiver optical waveguide and the second receiver optical waveguide for selectively reflecting the dropped channel or transmitting the dropped channel to the second receiver waveguide. A second retransmission waveguide (130, 182) in optical communication with the selectively reflective means receives a reflected optical signal. A method of dropping a select channel of a multi-channel optical signal propagated along a main optical waveguide without loss of data includes directing the multi-channel optical signal from the main optical waveguide to an input waveguide. The receiver waveguide is optically aligned with the input waveguide. A tunable transmission filter is provided in optical communication between the input and receiver waveguides. The transmission filter is tuned to drop a select channel to the receiver optical waveguide and to reflect the remaining channels of the multi-channel optical signal to a retransmission optical waveguide in optical communication with the main optical fiber. All dropped channels are reflected for repropagation along the main optical waveguide while the tunable transmission filter is tuned between first and second select channels. The transmission filter (106, 164) may be a wedged-etalon having a cavity that varies uniformly in width between a widest operative end and a narrowest operative end along a filtering axis in optical communication between the input and receiver waveguides. An actuator (107) moves the wedged-etalon out to select positions between the widest and narrowest operative ends to drop a select channel.
