Abstract:

We use switchable fiber-gratings in higher-order-mode fibers to demonstrate a wavelength-continuous adjustable dispersion-compensator (tuning range ~ 435 ps/nm) that is broadband (30 nm) and low loss (average ~ 3.7 dB). 40 Gb/s transmission tests reveal penalty-free operation

Introduction

Long haul, high-speed transmission links are designed with tight tolerances on dispersion maps. Statistical variations in the dispersion of transmission fibers, amplifier-hut spacings or ambient conditions introduce the need for broadband tunable dispersion compensators (TDC). Existing TDCs, such as filters with variable phase response^1–3 and sampled fiber-Bragg gratings^{4, 5}, possess a periodic spectral response that is tailored to specific signal bandwidths and channel spacings. Thus, they work only within a restricted passband for each channel.
