摘要:
基于三维有限差分束传输法(FD-BPM)对平面光波导器件中的关键元件之一——平面锥形模斑转换器作了深入的研究.对线性和数种非线性侧面边界的模斑转换器进行了数值仿真和对比,分析了平面锥形模斑转换器侧面边界函数对耦合损耗的影响,以及模斑转换器中模场分布随传输距离的变化.确定了不同长度的平面锥形模斑转换器的最佳侧面边界,指出长度在200~1 000 μm范围内具有余弦边界的平面锥形模斑转换器性能最佳.并且发现,光纤中的出射光进入模斑转换器以后,光波模式会逐渐发生变化,并最终转化为单模.
Abstract:
The tapered optical waveguide spot-size converter, which is one of the key components in the variety of planar waveguide devices, was investigated by computer simulations based on 3D-FD beam propagation method. Lightwave transmissions in the special spot-size converters with linear and different nonlinear boundaries were simulated and compared with each other,and the transformation of the mode field distribution with the distance in the optical waveguide spot-size converter was analysed. It is shown that the spot-size converter with cosine distributed boundary in the length region of 200-1000 μm provides excellent performance,and the lightwave mode in the spot-size converter varies gradually and transforms into single mode finally.
