Optical modulation of interconnection strength using amorphous $As_2S_3$ thin film

비정질 $As_2S_3$ 박막을 이용한 광연결 세기의 변조방식

A method for optical representation and modulation of synaptic interconnections between neurons using photoanisotropic amorphous As2S3 thin film is discussed. Experimental results show that the proposed method can be used for the representation of not only excitatory synaptic connections but also inhibitory synaptic connections. Applications of the method to the implementation of optical learning machine is also discussed.
