摘要： The present invention relates in general to SPR sensors in which the sensing element is a planar lightpipe. More specifically, a planar lightpipe sensor configuration for measurement of SPR at a single angle operation is provided. The lightpipe of this sensor is beveled to facilitate coupling of substantially collimated white light, preferably TM polarized white light, at a selected single angle that excites SPR at the sensing area. Angle of incidence on the SPR sensing area is determined by bevel angle used. This embodiment is a zero order sensor in the sense that it allows measurement for a given analyte at only a single angle of incidence. In this embodiment, however, the lightpipe can have a plurality of SPR sensing area across its width to provide for multichannel sensing. Refractive index sensitivity of this configuration is estimated as 4.times.10.sup.-5 RI units.

摘要： A channel detection system includes an interferometer coupled to a spectrum analyzer to differentiate additive spontaneous emission (ASE) noise from optical channels in a dense wave-division multiplex (DWDM) signal. It is assumed that channels, if present, are centered at frequencies corresponding to a standardized channel grid. The relative delay of the interferometer is chosen to be greater than the coherence time of the ASE noise but less than the coherence time of the channels with the interferometer's free spectral range set to an integer divisor of the channel-to-channel frequency spacing of the grid such that active channels experience a high degree of interference. The phase delay of the interferometer is then adjusted to maximize the interference at each grid-aligned frequency. The spectrum-analyzed outputs are compared (e.g., subtracted from one another and then thresholded) to determine the channels present in the DWDM signal.
