“…Recently, we introduced the concept of shifting the transmission band from the conventional C-band to 2 µm [4,5], due to the potential ultra-low loss (~0.1 dB/km) HC-PBGF may provide [6,7], in addition to its near-vacuum latency and lower nonlinearity when compared to standard SMF [8]. Thulium-doped fiber amplifiers (TDFA) which operate over a wide bandwidth spanning from ~1.80 µm to 2.05 µm are also available at this waveband [9] and their use in a transmission experiment has been demonstrated [5].…”

“…Moreover, the increasing availability of telecommunication-grade optical components at 2 µm, such as lasers [10], modulators and photo-detectors (PD) [11], are making transmission experiments at 2 µm practical. We previously presented in [4] that either direct laser modulation, or external modulation can be implemented in the 2 µm region, and successfully demonstrated the first WDM transmission experiment over 290 m of HC-PBGF. In addition, we recently reported error-free 81 Gbit/s WDM transmission at 2 µm over 1.15 km of low-loss HC-PBGF [12].…”

Abstract: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, spanning a 36.3 nm wide wavelength range. WDM transmission was successfully demonstrated over 1.15 km of low-loss hollow core photonic bandgap fiber (HC-PBGF) and over 1 km of solid core fiber (SCF). We conclude that the OSNR penalty associated with the SCF is minimal, while a ~1-2 dB penalty was observed after the HC-PBGF probably due to mode coupling to higher-order modes. 594-596 (2011).

“…First, OOK signal generation using an external modulator at a data rate of up to 8.5 Gb/s combined with 3-channel Fast-OFDM binary phase shift keying (BPSK) signals via direct laser modulation (5 Gb/s) were demonstrated, resulting in a total capacity of 20 Gbit/s transmitted over 50 m of standard single mode fiber [16]. Following that 4-channel transmission of 16 Gb/s signals over 290 m of HC-PBGF was demonstrated [17]. Recently, 8-channel coarse WDM transmission over 1.15 km of HC-PBGF was shown using 4-channel 12.5 Gb/s OOK external modulation and 4-channel 7.7 Gb/s 4-ASK Fast-OFDM direct modulation [18], providing a total capacity of 81 Gb/s.…”

Abstract-The 2-µm wave band is emerging as a potential new window for optical telecommunications with several distinct advantages over the traditional 1.55µm region. First of all, the Hollow-Core Photonic Band Gap Fiber (HC-PBGF) is an emerging transmission fiber candidate with ultra-low nonlinearity and lowest latency (0.3% slower than light propagating in vacuum) that has its minimum loss within the 2-µm wavelength band. Secondly, the Thulium-doped fiber amplifier that operates in this spectral region provides significantly more bandwidth than the Erbium-doped fiber amplifier. In this paper we demonstrate a single-channel 2-µm transmitter capable of delivering >52 Gbit/s data signals, which is twice the capacity previously-demonstrated. To achieve this we employ discrete multi-tone (DMT) modulation via direct current modulation of a Fabry-Perot semiconductor laser. The 4.4-GHz modulation bandwidth of the laser is enhanced by optical injection locking, providing up to 11 GHz modulation bandwidth. Transmission over 500-m and 3.8-km samples of HC-PBGF is demonstrated.

“…Furthermore, the development of the various critical optical devices (e.g., transmitters, receivers, filters etc.) needed to enable high capacity WDM transmission is also well underway and the first WDM experiments have also now been undertaken [132]. If the predicted ultralow loss of HC-PBGFs can be realized, then all of the key components required to build high capacity communication links at this emerging waveband are now in place.…”

Hollow-core photonic bandgap fibers: technology and applications

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 promise to deliver a unique range of optical properties that are simply not possible in conventional fibre types. HC-PBGFs have the potential to overcome some of the fundamental limitations of solid fibres promising, for example, reduced transmission loss, lower nonlinearity, higher damage thresholds and lower latency, amongst others. They also provide a unique medium for a range of light: matter interactions of various forms, particularly for gaseous media. In this paper we review the current status of the field, including the latest developments in the understanding of the basic guidance mechanisms in these fibres and the unique properties they can exhibit. We also review the latest advances in terms of fibre fabrication and characterisation, before describing some of the most important applications of the technology, focusing in particular on their use in gas-based fibre optics and in optical communications.
