本文报道了一种新的非线性光学材料ZnS·BaSO4,其粉末二次谐波效率大约是KDP的103倍。并利用电子衍射对其结构特性作了分析。
All-optical binary convolution with a photonic spiking vertical-cavity surface-emitting laser (VCSEL) neuron is proposed and demonstrated experimentally for the first time, to the best of our knowledge. Optical inputs, extracted from digital images and
