Techxplore  January 21, 2022 The inherent optoelectronic noises make the photonic systems error-prone in practice. To mitigate and harness noises in photonic computing systems a team of researchers in the US (University of Washington University, Duke University, University of Maryland) has designed and demonstrated a photonic generative network as a part of a generative adversarial network (GAN). The network is implemented with a photonic core consisting of an array of programable phase-change memory cells to perform four-element vector-vector dot multiplication. The GAN can generate a handwritten number (“7”) in experiments and full 10 digits in simulation. They developed an optical […]
