Study on photonic graphene multi-bearing detection sensor

为了实现多方位的探测,针对光子石墨烯特殊的光传输机制,在了解光子石墨烯谷依赖波束输运的基础上,选择光子石墨烯的相关参数,并设计了合适的结构模型,用COMSOL软件对其进行仿真计算。结果表明:在二维光子石墨烯结构中放置点源,点源发射的光束在平面内可以沿6个方向进行传输,此结构用于传感器即可以实现多方位的探测,可为多方位探测传感器的研制提供新的思路。

In order to achieve multi-bearing detection,on the basis of understanding the valley-dependent propagation of light in photonic graphene,selecting related parameters of photonic graphene,design reasonable structure model,and simulation calculation is carried out by COMSOL software. The simulation result shows that point source is put in 2D photonic grapheme structure the light beams,from point source transmit along six directions in plane. The sensor using this photonic graphene structure can realize detection in multiply bearing.These research contribute to the development of multi-bearing detection sensor.
