微光学在光束整形、准直、聚焦、成像等领域有着广泛的应用。我们使用飞秒3D打印来制造自由形状的微光学元件。我们的方法提供亚微米级的精度，因此即使是在单模光纤上也可以直接制造。我们通过写入不同的准直光学元件、环形透镜、用于强度光束整形的高达10阶多项式的自由曲面以及用于圆偏振滤波的手性光子晶体来展示我们的方法的潜力，所有这些都排列在单模光纤的纤芯上。我们通过分析输出图案以及干涉测量表征表面来确定光学系统的精确度。我们发现与数值计算很好地吻合。微光学的3D打印可以获得足够的性能，从而实现快速成型以及光束整形和成像设备的生产。将自由曲面光学与微纳光学相结合，可以实现波前整形、位相工程、k空间和偏振控制。这里，Gissibl等人。使用飞秒3D打印来制造自由形状的光学元件，提供亚微米的精度，因此可以直接在单模光纤上制造。
Micro-optics are widely used in numerous applications, such as beam shaping, collimation, focusing and imaging. We use femtosecond 3D printing to manufacture free-form micro-optical elements. Our method gives sub-micrometre accuracy so that direct manufacturing even on single-mode fibres is possible. We demonstrate the potential of our method by writing different collimation optics, toric lenses, free-form surfaces with polynomials of up to 10th order for intensity beam shaping, as well as chiral photonic crystals for circular polarization filtering, all aligned onto the core of the single-mode fibres. We determine the accuracy of our optics by analysing the output patterns as well as interferometrically characterizing the surfaces. We find excellent agreement with numerical calculations. 3D printing of microoptics can achieve sufficient performance that will allow for rapid prototyping and production of beam-shaping and imaging devices. Combining freeform optics with micro- and nano-optics can permit wavefront shaping, phase engineering, k-space and polarization control. Here, Gissibl et al. use femtosecond 3D printing to manufacture free-form optical elements, giving sub-micrometre accuracy so that direct manufacturing on single-mode fibres is possible.
