ReDON: Recurrent Diffractive Optical Neural Processor with Reconfigurable Self-Modulated Nonlinearity
The paper introduces ReDON, a novel recurrent diffractive optical neural processor that overcomes the limitations of static passive masks by employing reconfigurable, self-modulated nonlinearity inspired by gated linear units, thereby significantly enhancing computational expressivity and task performance on image benchmarks with minimal power overhead.
