AB  - We propose an alternative device concept which represents the foundation for future fully photon operated logic circuits based on an optically active medium. The device has the potential to decrease energy consumption and simultaneously to significantly increase computational operation speed. We call this all-optical switch device a “transmistor”, since in this alternative concept a controllable train of photon pulses (optical gate) initializes substantial changes of the optical transmittance of an optically active medium by inducing structural changes therein. First results of a fully photon operated prototype of a transmistor device based on a layered phase change Ge1Sb2Te4 nano-membrane are presented. The transmittance changes of the nano-membrane‘s material structure determine the transmitted optical power in the functionally arranged optical device.
