Superpositions of coherent light waves typically interfere. We present superpositions of up to six plane waves that defy this expectation by having a perfectly homogeneous mean square of the electric field. For many applications in optics, these superpositions can be seen as having a homogeneous intensity. Our superpositions show interesting one-, two-, and three-dimensional patterns in their helicity densities, including several that support bright regions of superchirality. Our superpositions might be used to write chiral patterns in certain materials, and, conversely, such materials might be used as the basis of an “optical helicity camera” capable of recording spatial variations in helicity.

多达六个平面波的叠加，没有电场干扰

相干光波的叠加通常会干扰。我们提出了多达六个平面波的叠加，这些叠加通过具有完全均匀的电场均方根来克服这种期望。对于光学中的许多应用，可以将这些叠加视为具有均匀的强度。我们的叠加在其螺旋密度上显示出有趣的一维，二维和三维模式，包括支持超手性明亮区域的几种模式。我们的叠加可以用于在某些材质中编写手性图案，相反，此类材质可以用作能够记录螺旋度空间变化的“光学螺旋相机”的基础。
