What's happening in fiber-to-the-home?

situations: with nonthreshold interaction of the laser beam with the NLC, and with the threshold interaction (known as optical Freedericks transition). Some characteristic dependencies are presented in Figs. 2 and 3. For nonthreshold case, the sensitivity of the NLCreorientation magnitude to the speed of motion was found to be of the order of ANlAv -0.2 ()*m/s)-’ [for the beam power P = 722 mW. The effect of the transverse motion is stronger for the for critical character of interaction light and NLC, AN/Av 1 (pm/s)-’]. The following simple expression allows us to gain some physical insight into the problem, and to evaluate the characteristic parameters:
