Abstract
Provided is a wavelength converter having a simple and low-cost structure. The wavelength converter generates converted light having a wavelength different from that of input light. The wavelength converter includes (1) a pump light source that outputs pump light, (2) an optical multiplexer that combines and outputs input light and the pump light, (3) 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 (4) zero-dispersion wavelength adjusting means that adjusts a zero-dispersion wavelength of the first optical fiber.
