A single-fibre, two-moded interferometer has been constructed. A nonlinear switch based on this interferometer has been demonstrated in which an argon ion laser probe signal is modulated by a dye laser pump signal, inducing a change in refractive index through the optical Kerr effect. A power-length (PL) product for 100% modulation of 380 Wm has been measured.
