Abstract
A wavelength conversion device includes a nonlinear optical crystal, a guide light source configured to provide a guide light traveling in a first direction within the nonlinear optical crystal such that a thermal waveguide penetrating the nonlinear optical crystal is formed, a signal light source configured to provide a signal light having a first wavelength (λ1) and traveling in a second direction opposite to the first direction through the thermal waveguide, and a pump light source configured to provide a pump light having a second wavelength (λ2) and traveling in the second direction through the thermal waveguide, wherein an output light including a wavelength component corresponding to a sum of energies of the first wavelength (λ1) and the second wavelength (λ2) is provided from the thermal waveguide.
