摘要:

在本文中,我们提出了理论研究的折射率映射,实现高斯到J 0-贝塞尔-高斯转换。我们从理论上证明了这种装置的可行性,通过解决电磁逆问题。计算的转换效率为90%。从光束转换效率、自再生和通过不透明障碍物的传播获得的理论结果表明,折射率的2D渐变折射率图可以用于将高斯光束转换为J 0-贝塞尔-高斯光束。据我们所知,这是第一次演示这种光束变换的二维折射率映射,这是完全集成在硅光子为基础的平面光波电路(PLC)。这一概念装置对于一系列新技术的最终发展具有重要意义,如微型光镊、光阱、光束整形和非线性光束二极管激光器。

英文摘要:

In this paper, we present the theoretical studies of a refractive index map to implement a Gauss to J0-Bessel-Gauss convertor. We theoretically demonstrate the viability of such device by solving the inverse electromagnetic problem. The computed conversion efficiency is 90%. The theoretical results, obtained from the beam conversion efficiency, self-regeneration, and propagation through an opaque obstruction; demonstrate that a 2D graded index map of the refractive index can be used to transform a Gauss beam into a J0-Bessel-Gauss beam. To the best of our knowledge, this is the first demonstration of such beam transformation by means of a 2D index-mapping which is fully integrable in silicon photonics based planar lightwave circuits (PLC). The concept device is significant for the eventual development of a new array of technologies, such as micro optical tweezers, optical traps, beam reshaping and non-linear beam diode lasers.
