An all-fiber method to measure the wave-particle duality of light

  • 摘要: 提出一种结构简单、实验现象明显的光波粒二象性观测方案,本方案以波的相干叠加突出显示光的波动性,以粒子在50/50分束器的路径随机选择特性突出显示光的粒子性.以衰减强激光脉冲为光子源,在实验室获得的干涉对比度超过99%,单粒子特性超过90%.实验结果表明此方案有望在实际得到广泛应用.
    Abstract: A new scheme with very simple implementations giving obvious experimental results has been demonstrated to reveal the particle and wave duality of light. The scheme demonspates the wave property of light by coherent superposition and the particle property of light by random path selection though a 50/50 beam splitter. Preliminary experiments showed high interference visibility of 99% and the particle nature of light as high as 90% by using a highly attenuated pulsed laser as a single photon source. This scheme displays both the wave and particle nature of light though a simple experimental setup, which makes it a quite promising schem for revealing the property of light.
