New optical computation method bypasses diffraction limits using superoscillations

Researchers have demonstrated a novel method for optical computation using superoscillatory functions, which allows for the processing of functions with bandwidths exceeding the diffraction limit of light. This approach encodes a scalar argument onto a wavefront, which is then processed by a fixed diffractive wave processor to generate approximate function outputs in parallel. The technique allows for the synthesis of complex-valued superoscillatory functions and utilizes a multiplexed architecture to evaluate distinct functions simultaneously, even when their harmonic content surpasses that of the optical input encoding. This establishes functional superoscillation as a principle for wave-based computation, separating functional bandwidth from physical wave bandwidth in analog optical systems. AI
