摘要

随着光波通信网络对带宽的需求不断增加。信道间距≤0.8 nm的DWDM起着重要的作用。这就要求DWDM器件在EDFA平增益波长范围内具有平顶传输频谱、高通道隔离和低插入损耗[1]。本文演示了采用apodized fbg和带通WDM滤波器(BWDM)的具有0.4 nm信道间距的DWDM器件。

High Performance DWDM Multiplexer and Demultiplexer with a 0.4 nm Channel Spacing

With an ever increasing demand for bandwidths in lightwave communication networks. DWDM with a channel spacing of ≤0.8 nm plays an important role. This requires DWDM devices with a flat-top transmission spectrum, a high channel isolation and low insertion loss for the EDFA flat gain wavelength range [1]. In this paper, DWDM devices with a 0.4 nm channel spacing using apodized FBGs and bandpass WDM filters (BWDM) in cost-effective structures are demonstrated.
