英国巴斯大学的研究小组开发出一种具有带隙结构的光纤(PBG光纤)。这种光纤与以往的光纤相比,其光的传输方式有着本质上的不同。与以往那种在光纤内全反射的同时传输光的光纤相反,此光纤利用了与周期性结构相对呈铅直方向传输光波时,可提取某个特定频率的光波这样的特性。
A research team at the University of Bath in the UK has developed a fiber with PBG (PBG fiber). This optical fiber compared with the previous optical fiber, the optical transmission is essentially different ways. In contrast to conventional optical fibers that transmit light simultaneously with total internal reflection within the fiber, the fiber takes advantage of the ability to extract light waves at a particular frequency when transmitting light waves in a vertical direction relative to the periodic structure.
