Paper Abstract

A fused-tapered fiber coupler, which is fabricated by fusing and elongating two single-mode fibers, exhibits a nonlinear coupling characteristics when it is excited with an intense light, since an intensity-dependent index of refraction is induced in fiber couplers due to optical Kerr effect. An abrupt change of power transmission at coupled and through ports in the coupler can be observed at certain wavelength of incident light and it was found that the critical wavelength is shifted into a longer wavelength as the incident power increases. The experimental verification using a mode-locked Ti:sapphire laser that produces 50 femtosecond pulses at wavelengths of 800 - 850 nm with a repetition rate of 80 MHz is followed by the theory.
