Paper Abstract

Now a new technology has emerged called “Fiber Bragg Gratings” which allows very narrow band width filters to be made in optical fibers. These fiber gratings have been applied to the communications industry at the 1.55 micron telecommunications wavelength, but there is evidence that the same technology will work at the 589 nm wavelength of interest to Na Fluorescence Lidar. Because of its high reflectivity (99%) and narrow band width (0.1nm), it can be used instead of present dielectric interference filters and Fabry-Perot etalon in the Lidar receiver, which will drastically improve the optical efficiency and the signal-to-noise ratio of Lidar. It will also drastically simplify the Lidar receiver.
