论文摘要
光学是一个有前途的平台,可以帮助实现下一代快速,平行和节能计算。我们展示了可重新配置的自由空间光学乘数,该光学乘数能够并行3000多个计算,使用具有像素分辨率仅为340x340的空间光调节器。这使矢量矩阵乘法和并行矢量矢量乘法量具有高达56的矢量乘法。我们的设计是第一个同时支持可重新配置,大尺寸和实价的线性代数操作的光学实现。这样的光学乘数可以用作特殊用途的光学处理器的构建块,例如光学神经网络和光学机器。
Optics is a promising platform in which to help realise the next generation of fast, parallel and energy-efficient computation. We demonstrate a reconfigurable free-space optical multiplier that is capable of over 3000 computations in parallel, using spatial light modulators with a pixel resolution of only 340x340. This enables vector-matrix multiplication and parallel vector-vector multiplication with vector size of up to 56. Our design is the first to simultaneously support optical implementation of reconfigurable, large-size and real-valued linear algebraic operations. Such an optical multiplier can serve as a building block of special-purpose optical processors such as optical neural networks and optical Ising machines.
