Abstract

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.
