Magnetic photoNic crystal

The magnetic photoNic crystal (じせい photo Nic plasma British: magnetophotonic crystal) refers to the thing using the magnetic material to photoNic crystal. It is abbreviated to MPC.

Principle, structure

The structure that materials more than two kinds with a different refractive index were arranged on a wavelength scale of the light periodically is called photo Nic crystal (PC). The photoNic crystal,

• Like the bandgap that does not permit electronic existence in a solid crystal existing, I develop a bandgap (photoNic bandgap) that does not permit the existence of the photon.
• Group speed of the light of the band edge wavelength decreases.

I have などの characteristic [¹].

The magnetic photoNic crystal does structure across the magnetic body with dielectric multilayer film, and a local existence mode develops by the class of these defects in photo Nic bandgap. Due to this phenomenon; the magnetic photoNic crystal,

• I increase magneto-optic effect while having high transmissivity.
• I produce magnetization evocation second harmonics outbreak (MSHG).
• Magnetic field control of the light is enabled.

I have などの characteristic [¹].

Actually, as a result of having performed manufacture, an evaluation of the structure using Bi:YIG which is a transparent magnetic body in the defect layer, increase of the big faraday angle of rotation of approximately 10 times of the bed film is confirmed while having high transmissivity [¹].
