Analytical formulas for a class of tunable random electromagnetic beams propagating in a turbulent atmosphere through a complex optical system are derived with the help of a tensor method. One finds that the far field intensity distribution is tunable by
We present an ultrabroadband, high-speed wavelength-swept source based on a self-modulated femtosecond oscillator. Photonic crystal fiber was pumped by a mode-locked

提出了一种基于神经元网络后向传播算法的二元光学设计新方法，该法的突出特点是可以获得较快的收敛速度和较好的均匀性。最后给出6个Dammann光栅的设计结果。
In this paper, we propose and numerically investigate a novel circular lattice photonic crystal fiber (CL-PCF) using controllable GeO2 doped silica, suitable for modes carrying quantized orbital angular momentum (OAM). Large effective index sep

研究了仪器函数形状稍微偏离对称三角形情形下的三刺激值计算问题,探索了其对应的最优加权表。结果发现,最优权重可以通过求解三个系数矩阵的线性方程组来得到,且系数矩阵是对称正定三对角矩阵。将本课题组前期研究获得的最优加权表方法推广到仪器函数形状为非对称三角形的情形。仿真结果表明,对于10 nm和20 nm测量间隔,最优加权表方法的精度优于三点和五点校正方法;对于5 nm测量间隔,最好的计算方法是先对测量数据进行三点校正,再使用直接选取方法计算三刺激值。
