Abstract

A scheme of light coupling into optical fiber was proposed and studied theoretically. Light coupling is realized by excitation of photorefractive oscillator. It consist of fiber facet and phase conjugate mirror based on four wave mixing. The scheme is self-adaptive and can tolerate rather large angular and lateral displacement of fiber end. As a result of numerical simulation we obtain that about 50 percent of reading pump wave intensity can be injected into the fiber. Coupling efficiency is decreased by factor of two when the lateral displacement of fiber end about 1000 micrometers .
