摘要 |
A light limiter (21) is described which can control the generation of an optical surge, includes few components, and has high reliability. The light limiter includes a parametric amplification element (22) for parametrically amplifying an input signal light, and a wavelength selection element (23) for removing a wavelength component excepting a specified wavelength, from among the signal light output from the parametric amplification element. <IMAGE> |
