摘要

我们提出了一种新的波长滤波器，使用光栅辅助垂直反向耦合器的加丢复用器(ADM)。计算结果表明，通过对器件参数的优化，该滤波器的带宽可以窄到小于1 nm，并且易于控制。我们成功地制作了基于inp的半导体滤波器，并证明了滤波带宽窄至0.7 nm，这与我们的计算一致。

Proposal of new narrow-band wavelength filter using grating-assisted vertical contra-directional coupler

We propose a novel wavelength filter using a grating-assisted vertical contra-directional coupler for an add and drop multiplexer (ADM). It is predicted from our calculations that the bandwidths of the filter can be narrow less than 1 nm and easily controllable by means of the optimization of the device parameters. We have successfully fabricated the InP-based semiconductor filter and also demonstrated filtering bandwidth as narrow as 0.7 nm which is consistent with our calculations.
