    Abstract: 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 bulk optic (de)multiplexer (10) consists of a fiber pigtail array (20), a focusing optic (18) and a wavelength dispersive element or grating (16) in optical alignment along an optical axis (22). The focusing optic is rigidly affixed to the frame and the fiber pigtail array (20) and wavelength dispersive element (16) are attached by adjustable connectors (112, 56, 340) to facilitate al ignment.

    Abstract: A fiber pigtail template assembly (10) includes first and second silicon wafers (12, 14) each having a planar surface (22, 30) with a plurality of corresponding grooves (24, 32) therein extending from a leading edge toward a trailing edge. The plurality of corresponding grooves (24, 32), with the planar surfaces in abutment and the corresponding grooves aligned define a plurality of fiber channels (18). The first and second silicon wafers further cooperatively define a receptacle (26, 34) between the fiber channels and the trailing edges of the first and second silicon wafers with the planar surfaces of the silicon wafers in abutment with the grooves aligned. A minor diameter leading portion of an optical fiber (52) is received in each fiber channel and the receptacle is sized to receive major diameter trailing portions (54) of each fiber without causing a bending radius of the fiber sufficient to materially degrade wavelength propagation.

    Abstract: An apparatus and method are provided employing a single set of reduced-cost optics for (de)multiplexing optical signals whereby the resultant signals have a flat-top response with increased channel spacing. One aspect of the present invention uses an optical interleaver (310) to separate channels from an input multichannel (multiplexed) optical signal (302) with a select channel spacing into, for example, two input signals consisting of alternating channels at twice the select channel spacing. The separated signals are then directed to a multiple-input, such as dual-input, (parallel)(de)multiplexer device (320) which further spacially separates the channels for coupling with single channel transmission fibers (322 1-n , 324 1-n ). The input fibers to the (de)multiplexer are preferably offset relative to each other to accommodate channel shift resulting from the interleaver.

A diffraction grating (22) 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 (24) of the diffraction (22) have spacing which varies according to an algorithm such that a portion of the optical signal diffracted by each groove (24) 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.
