Abstract :
All-optical switching in Er3+-doped fiber Bragg grating was investigated. The response time is not limited by the radiative relaxation but by the cooperative ion interaction induced fast nonradiative relaxation in the high concentration Er3+-doped fiber. A signal modulation depth of 37% was measured when a 300 mW of 1480 nm pump was modulated at 5 kHz.
