Design of Task-Specific Optical Systems Using Broadband Diffractive Neural Networks [PDF]
Light: Science & Applications (2019), 2019 We report a broadband diffractive optical neural network design that simultaneously processes a continuum of wavelengths generated by a temporally-incoherent broadband source to all-optically perform a specific task learned using deep learning. We experimentally validated the success of this broadband diffractive neural network architecture by ...
