Celebrating the 20^ th anniversary of Optics Express, this paper reviews the evolution of
optical fiber communication systems, and through a look at the previous 20 years attempts to …

Optical communication technology has been advancing rapidly for several decades,
supporting our increasingly information-driven society and economy. Much of this progress …

We report the first experimental realization and detailed characterization of thulium doped
fiber amplifiers (TDFAs) specifically designed for optical communications providing high …

Today's optical communication systems are fast approaching their capacity limits in the
conventional telecom bands. Opening up new wavelength bands is becoming an appealing …

Phase-change materials (PCMs) and compounds enable a combination of features for
implementing advanced and multifunctional nanophotonic applications. Possessing …

Since the early conceptual and practical demonstrations in the late 1990s, Hollow-Core
Photonic Band Gap Fibres (HC-PBGFs) have attracted huge interest by virtue of their …

We present the first in-band diode-pumped TDFAs operating in the 2 µm wavelength region
and test their suitability as high performance amplifiers in potential future telecommunication …

Recently, 2-μm wave band has gained increasing interest due to its potential application for
next-generation optical communication. But the development of 2-μm optical …

We show for the first time 100 Gbit/s total capacity at 2 µm waveband, using 4× 9.3 Gbit/s 4-
ASK Fast-OFDM direct modulation and 4× 15.7 Gbit/s NRZ-OOK external modulation …

The first demonstration of a hollow core photonic bandgap fiber (HC-PBGF) suitable for high-
rate data transmission in the 2 µm waveband is presented. The fiber has a record low loss …
