Overview

narrow bandwidth filter spectrum

In this IXC-FBG-PS design, a Phase Shift (PS) is introduced within the middle of the stop band. This PS will lead to a sharp resonance peak visible in the transmission spectrum response and features less than 1 dB of insertion loss.

Our narrow bandwidth transmission filter can be used for telecom or The IXC-FBG-PS can be used as a narrow band transmission filter in telecom as well as in sensing applications. This product can also be used as a cavities of distributed feedback (DFB) fiber laser.
