摘要： A photoreceptor protein-based spectrophotometer may include a field-effect transistor and a photoreceptor protein on the field-effect transistor (FET), the photoreceptor protein exhibiting change in electrical properties by absorbing light and being activated. Since the spectrophotometer can convert the light absorbed by the photoreceptor protein to an electrical signal using the FET, it can mimic human vision by using human photoreceptor proteins. The spectrophotometer can measure the color, intensity, etc. of light of broad wavelength ranges as in human vision. Thus, the spectrophotometer can be applied to the development of artificial vision, etc.

摘要： A plasmonic all-optical switch includes a graphene layer, a first dielectric layer located on the graphene layer, a nano-antenna located on the first dielectric layer, and a second dielectric layer located on the nano-antenna. An incident beam is propagated by means of a surface plasmon wave generated at an interface between the graphene layer and the first dielectric layer. Further, localized surface plasmon resonance is selectively generated at an interface between the nano-antenna and the second dielectric layer by means of a pump beam incident to the nano-antenna to decrease an intensity of the incident beam. The plasmonic all-optical switch may operate at an ultrahigh speed just with a small light energy without any electric method, greatly reduce power consumption of an IT device by applying to an all-optical transistor or the like, and increase a processing rate.
