摘要：
We report on ongoing work with a compact all-optical recurrent neural network with 16 x 16 channels and 256 x 256 reconfigurable interconnects (weights). We will present the optical setup and report on experimental work with the system and its building blocks. The microlens-based setup shows excellent imaging properties and easy alignability. After optimizing the setup, losses could be reduced by more than an order of magnitude. The system performance is currently limited by inhomogeneities of the thresholding device.
