Within the range from 0 to 1the transmissivity of fused tapered fiber reflector as a conic function of the departure of the coupling-ratio from 50∶50 was examined theoretically and experimentally. Bending the fiber in loop-cavity causes no obvious change. Howevertwist and the radial pressure change the transmissivityobviouslyproducing birefringence in the fiber core. Temperature changes the transmissivity through the induced departure of the coupling-ratio. Constructed with a broad-band 3dB fused tapered fiber couplerthe reflector shows total reflection. A pulse was observed at the beginning of the formation of the transmitted beam. Increasing the input intensity causesthe rise-time and the fall-time of the pulse to decrease, while the width of the pulse and the steady state value of the transmitted power to increase.
