论文摘要
我们提出了通过多平面光转换（MPLC）实现的波长模式分散器。据我们最大的知识，可以同时对波长和空间模式进行分类。我们首先通过一系列相位掩模来证明纯波长排序，例如，可以在高功率波长束组合（WBC）或粗波长划分多路复用（CWDM）中找到应用。然后，我们仅使用5个相掩模的4波长3模式分散器的设计设计。插入损失（IL）和模式依赖损失（MDL）低至1.27 dB和2.45 dB。
We propose a wavelength-mode sorter realized by multi-plane light conversion (MPLC). For the first time, to our best knowledge, wavelengths and spatial modes can be sorted simultaneously. We first demonstrate pure wavelength sorting by a series of phase masks, which could find applications in high-power wavelength beam combining (WBC) or coarse wavelength-division multiplexing (CWDM), for example. We then present a design of a 4-wavelength, 3-mode sorter using only 5 phase masks. Insertion loss (IL) and mode dependent loss (MDL) as low as 1.27 dB and 2.45 dB can be achieved, respectively.
