Abstract

We describe a two-mode fiber switch made of a short length of erbium-doped fiber in which switching is accomplished by a nonlinearity that is resonantly enhanced by the dopant. In a 0.95-m fiber pumped with a 1.48-μm laser diode, a 906-nm signal is switched with only 8 mW of absorbed power at a signal absorption loss of 0.25 dB.

Measured dependence of the nonlinear phase shift on the absorbed pump power for a signal wavelength of 906 nm, a pump wavelength of 1.48 μm, and a fiber length of 3.4 m. Signal cold loss was 0.5 dB. The solid line is a linear fit to the data.

(a) Nonlinear phase shift as a function of signal wavelength for Pabs= 10 mW. The solid curve is a fit to a Gaussian line shape centered at 978 nm, with a linewidth of 24 nm and an offset of π/2. (b) Absorption spectrum for the same fiber as in (a). The solid curve is a fit to a Gaussian line shape (FWHM = 29 nm, centerline at 978 nm) with an offset of 0.26 dB/m. The dashed curve is a fit to a Lorentzian line shape (FWHM = 24 nm, same centerline and offset).
