Strategic Study of CAE 2004, Volume 6, Issue 12,   Pages 73-77

Abstract:

Dynamic routing and wavelength assignment in the WDM networks with.both dynamic service traffic andlimited-range wavelength conversion have been discussed.According to probability and limitation of wavelength conversion, a novel heuristic algorithm, whichcould achieve dynamic minimum cost routing and optimal virtual wavelength path, DMC - OVWP, is proposedWith separation and combination of routing and wavelength assignment subproblems, the algorithm optimizes

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4,   Pages 617-625 doi: 10.1631/FITEE.2200510

Abstract: 精确的、与波长相关的相位调制在许多领域中是必不可少的，比如超分辨成像、全彩色全息、微纳加工以及光通讯。这一要求很难通过单一的传统光学元件实现，一般需要使用多个光学元件组合完成。本文提出一种可以实现波长选择性波前整形的超表面设计方法。具体来说，本文设计了一种超表面，它能够对785 nm波长的光做涡旋相位调制，同时不影响590 nm波长的光保持原有相位分布。本文通过干涉仪以及对应点扩散函数的测量来验证不同波长下的波前分布。与已提出的空间复用方式以及色散工程的方法相比，我们提出的设计方法更加直接，优化难度小，适用于需要波长选择性编码的光学系统。本文所提平面光学器件对于需要波长选择性编码的光学系统具有重要应用意义。
