Selective launching of higher-order modes into an optical fiber with an optical phase shifter.
We demonstrate a simple, effective technique for launching higher-order modes into a double-mode optical fiber by using an optical phase shifter at the input end. The suppression of the lowest-order mode was measured (but not limited) to be 27 dB.
