Wavelength and polarization are two fundamental properties of light within which information can be encoded and (de)multiplexed. While wavelength-selective systems have widely proliferated, polarization-addressable active photonics has not seen notable progress, primarily because tunable and polarization-selective nanostructures have been elusive. Here, we introduce hybridized-active-dielectric (HAD) nanowires to achieve polarization-selective tunability. We then demonstrate the ability to use polarization as a parameter to selectively modulate the conductance of individual nanowires within a multi-nanowire system. By using polarization as the tunable vector, we show matrix-vector multiplication in a nanowire device configuration. While our HAD nanowires use phase-change materials as the active material, this concept is readily generalized to other active materials hybridized with dielectrics and thus has the potential in a broad range of applications from photonic memories and routing to polarization-multiplexed computing.

混合有源电介质纳米线中的偏振选择性可重构性

波长和偏振是光的两个基本属性，信息可以在其中编码和（解）复用。虽然波长选择系统已广泛普及，但偏振可寻址有源光子学并未取得显着进展，这主要是因为可调谐和偏振选择纳米结构一直难以捉摸。在这里，我们引入了混合活性电介质 (HAD) 纳米线来实现偏振选择性可调性。然后，我们展示了使用极化作为参数来选择性地调制多纳米线系统中单个纳米线的电导的能力。通过使用偏振作为可调谐矢量，我们展示了纳米线器件配置中的矩阵矢量乘法。虽然我们的 HAD 纳米线使用相变材料作为活性材料，
