본문내용
► For example, the hetero-PBG structure film is opaque for forward propagation, whereas it is transparent for backward propagation at 500nm
► Phase retarder layer affects the non- reciprocal transmission property.
► As refractive index anisotropy(Δn) is
Increased, hetero-PBG film has the non-reciprocal transmission property.
But, Δn is reduced, the non-reciprocal transmission propery disappears.
► Because the nematic liquid crysatal is used as an anisotropic layer(phase retarder layer), Δn can easily be varied by changing applied electircal field.
⇒ Non-reciprocal transmission property + tunable transmitted intensity
∴ optical diode that is electro-tunable
