nonlinear optical loop mirror


nonlinear optical loop mirror

[¦nän‚lin·ē·ər ¦ap·tə·kəl ′lüp ′mir·ər] (optics) A fiber-optic device in which a coupler splits the input light into two waves that travel in opposite directions around a fiber-optic loop and acquire different phases because of nonlinearities in the optical medium; the output power is very low for some phase differences and equals the input power for other phase differences.
