Paper Abstract

We experimentally demonstrate adaptive control of linearly polarized (LP) modes based on a fiber Bragg grating (FBG), where feedback for the adaptive algorithm is provided by the optical signal transmitted through and reflected by the FBG. In this approach, by maximizing the ratio of optical power transmitted and reflected by the FBG, we can selectively excite the LP01 and the LP11 modes at an optical wavelength associated with the appropriate FBG reflection peak. Combining this method with time-division-multiplexing, it should be possible to adaptively control guided modes at any desired location within a multimode fiber network.
