本研究研究了通过选择性区域外延生长的未涂覆和涂覆金的InP纳米线光子晶体阵列衍射光的偏振态。实验数据和时域有限差分模拟表明，衍射光束的偏振态强度和椭圆度可以由纳米线尺寸和金涂层控制，而衍射角随这些参数的变化保持不变。在纳米线周围沉积了一层名义上10nm厚的金膜，通过等离子体效应增强了衍射强度。这些结果表明，将入射线偏振光控制转换为圆偏振光或旋转线偏振光在光子集成电路中可以得到应用。偏振态对纳米线尺寸变化的高灵敏度在半导体计量、微芯片检测以及亚微米粒子检测领域开辟了新的前景。
This work investigates the polarization state of light diffracted from uncoated and gold‐coated InP nanowire photonic crystal arrays grown by selective area epitaxy. Experimental data and finite‐difference time‐domain simulations show that both the intensity and the ellipticity of the polarization state of the diffracted light beam can be controlled by the nanowire dimensions and gold coating, while the diffracted angle remains unchanged with respect to variations of these parameters. A nominally 10 nm‐thick gold film deposited around the nanowires enhances the diffraction intensity by plasmonic effects. These results demonstrate that the controlled conversion of incident linearly polarized light to circularly polarized or rotated linearly polarized diffracted light can find applications in photonic integrated circuits. The high sensitivity of the polarization state with respect to alterations of the nanowire dimension opens new prospects in the areas of semiconductor metrology and microchip inspection as well as for submicron particle detection.
