NON-LINEAR INTERFEROMETER |
摘要 |
An optical fibre, loop interferometer (31) is formed from germania doped silica which exhibits Raman scattering at a threshold intensity to provide a transmitted optical signal from port (49) of coupler (35) whose intensity is a sigmoid function of the intensity of an optical signal input at port (39). It finds application in optical switching and logic operations on optical pulses. |
