Highly stable optical add/drop multiplexer using polarization beam splitters and fiber Bragg gratings

Abstract

We demonstrate novel wavelength-division add/drop multiplexer employing fiber Bragg gratings and INPUT polarization beam splitters. The multiplexer is easy to fabricate without any special technique such as UV trimming, and yet shows very stable performance with less than 0.3-dB crosstalk power penalty in a 0.8-nm-spaced, 2.5-Gb/s-per-channel wavelength-division multiplexing (WDM) transmission system.
