Abstract

We demonstrate the switching of light in the near-infrared region ( 1.55 μ m ) through the manipulation of magnetic nanoparticles in a magnetic fluid by using another light in the visible region ( 0.532 μ m ) . The formation of a photonic gap is found in the magnetic fluid when a laser light or a magnetic field is applied. A shift of the photonic gap to longer wavelengths is observed with increasing laser power or magnetic field strength.
