Abstract:
1. A wavelength converter that generates converted light having a wavelength different from that of input light, the wavelength converter comprising: a pump light source that outputs pump light; an optical multiplexer that combines and outputs input light and the pump light; a first optical fiber that receives and guides the input light and the pump light that have been combined and output by the optical multiplexer and generates converted light using a nonlinear optical phenomenon that occurs while the first optical fiber guides the input light and the pump light, the first optical fiber being coiled; and zero-dispersion wavelength adjusting means that adjusts a zero-dispersion wavelength of the first optical fiber, wherein the zero-dispersion wavelength adjusting means adjusts a temperature of the first optical fiber, and wherein a temperature adjustment range of the first optical fiber adjusted by the zero-dispersion wavelength adjusting means is equal to or greater than 40° C.
