Nonlinear estimation of ring-down time for a Fabry-Perot optical cavity.
This paper discusses the application of a discrete-time extended Kalman filter (EKF) to the problem of estimating the decay time constant for a Fabry-Perot optical cavity for cavity ring-down spectroscopy (CRDS). The data for the estimation process is obtained from a CRDS experimental setup in terms of the light intensity at the output of the cavity. The cavity is held in lock with the input la...
متن کاملSpatial domain realization of the cavity ring-down technique in a plane Fabry–Perot cavity
We propose and demonstrate a spatial version of the cavity ring-down concept in which a photon flux decay is displayed along the spatial coordinate at the exit of a plane Fabry–Perot cavity. The photon decay signals are simulated based on a simple theoretical model combining ray optics and diffraction involved in the spatial ring-down generation, which are found to be in good accordance with th...
متن کاملObservation of Nonlinear Mode in a Cylindrical Fabry-Perot Cavity
We report the first observation of a nonlinear mode in a cylindrical nonlinear FabryPerot cavity. The field enhancement from cavity buildup, as well as the large (3) optical nonlinearity due to resonantly-excited 85Rb vapor, allows the nonlinear mode to form at low incident optical powers of less than a milliwatt. The mode is observed to occur for both the self-focusing and self-defocusing nonl...
متن کاملDouble-Cavity Fabry-Perot Filters
Fabry-Perot Filters are major candidates for use as demultiplexers in wavelength division multiple access networks. In this paper we investigate the crosstalk limitations of such filters, compare their performances, and optimize the filter design to minimize the crosstalk degradation. 1 Bol.h witli the al)()rt;l.orlo for informltaiou a.icl I)ecision Ssleties. ilT.

متن کاملMeasurement Technique Using a Fabry-Perot Cavity
A high precision measurement technique for characterizing the propagation loss in silica low-loss optical waveguides, based on measuring the contrast of a Fabry-Perot cavity, is demonstrated. The cavity consists of the waveguide coupled to two polarization-maintaining fibers, each end facet coated with dielectric mirrors, leaving the reflectivity as an adjustable parameter. The contrast is meas...
