▎ 摘　　要

NOVELTY - The electrode has a graphene layer which is transferred onto a substrate. The graphene in graphene layer has a light transmittance of 98% or more at a wavelength band of 1500-1700nm when the sheet resistance is 400 omega per square or less. The light transmittance in the wavelength band of 1500-1700nm is higher than the light transmittance in the wavelength band of 500-700nm. The graphene has a light transmittance of 100% or more in the wavelength range of 1500-1700nm when the sheet resistance is 400 omega per square or less. USE - Graphene transparent electrode formed between liquid crystal layer and glass substrate layer of silicon liquid crystal device-based wavelength selection switch (claimed). ADVANTAGE - The excellent light transmittance is realized in both the visible region and the infrared region. The light transmittance is significantly improved in the infrared region compared to the visible region, thus significantly improving the device's light output for optical communication in the infrared wavelength range. The graphene transparent electrode can be used as infrared sensor and infrared emitter, while having a low sheet resistance in the infrared region and maintaining a transparent property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a silicon liquid crystal device-based wavelength selection switch. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the silicon liquid crystal device-based wavelength selection switch. (Drawing includes non-English language text)
