- •
The EIT and slow light effect are achieved by our novel graphene based structure.
- •
Excellent tunability of wide wavelength range can be obtained only by a small change in Fermi energy level.
- •
The group velocity of incident light is reduced to more than 1/600 of that in vacuum.
- •
Position control is realized by designing a graded period grating.
