    摘要: A wavelength tunable light source includes an optical pulse generating section for generating an optical pulse; an amplitude control section for controlling the amplitude of the optical pulse generated by the optical pulse generating section by superimposing control light on the optical pulse to output a short optical pulse; and an optical frequency converting section for converting the frequency of the short optical pulse by launching the short optical pulse output from the amplitude control section into an optical nonlinear medium whose refractive index varies in response to the electric-field intensity of the incident light. The amplitude control section can be configured such that it carries out the time division multiplexing and outputs the short optical pulse, thereby constituting an optical pulse light source.
