Abstract

The direction of this paper is to describe the various analytical tools and measurement techniques used at SilkRoad to evalute the transmission-laser cavity control and optical beam train going into the electro optical modulator and subsequently into the otpical transmission fiber. The measurement values for the line width and the coherent length of the laser beam,and the subsequent Laguerre orders that are generated in the electro-optical modulator, are critical to the operation of the SilkRoad Optical Refractive Synchronization transmission technique. We begin the paper with the various analytical techniques that are used to calculate the line width and the coherency length. Following the analytical model, we describe the various measurement techniques and the subsequent data that results from our experiments.
