Sentences with phrase «optical transistor»

The researchers constructed the optical transistor by interconnecting the silver nanowire to a flake of molybdenum disulfide (MoS2).

The search for materials that can serve in optical transistors is complicated by additional property requirements.

With background signals washing out the intended output, necessarily computational qualities for optical transistors, such as their on / off ratio, modulation strength and signal mixing contrast have all been extremely poor.
