With the exponential growth of research in Machine Learning, so too has the demand for fast, energy efficient neuromorphic hardware, to execute such algorithms. Optics provides an attractive tool for implementing neuromorphic hardware due to is speed, low crosstalk and high parallelism. In particular, convolutional- and recurrent neural networks benefit from an optics implementation; by using passive optics to carry out convolution [1], and time division multiplexing to demonstrate a reservoir computer [2]. We present our results towards realizing an optical convolutional neural network with an atomic non-linearity [3] and an all-optical reservoir computer based on a delay loop with an additional optical random-access memory (RAM)[4].
