Abstract
To date, the most established all-optical Kerr switches are based on the nonlinear optical loop mirror (NOLM) scheme.1 NOLM’s utilize the nonlinear phase shift (which should be precisely π) imposed on a signal pulse by a control pulse, which can switch the state of interference between two parts of a signal pulse from constructive to destructive and vice versa. The interferometric nature of NOLM's makes them sensitive to vibration, polarization and pump power fluctuations,2 and makes it difficult to achieve complete and undistorted switching.
