“…Rather new modulation formats have been suggested over the time, which accommodate more bits per symbol [24]. These systems require coherent detection systems [25][26][27] at the receiver end, resulting in increased hardware and receiver complexity.…”

In this work a dispersion-compensated Raman amplifier has been cascaded with a single-pump parametric amplifier to build a dense wavelengthdivision multiplexed (DWDM) system. This hybrid system demonstrates a flat gain in the L-band. Our hybrid has been evaluated for a 25 GHz 96-channel system at 40 Gbps in the band spreading from 189 to 191.375 THz. The results demonstrate the gain larger than 16.9 dB and the gain ripple less than 5.82 dB, with no gainflattening technique used. The novelty of our design lies in combining dispersion compensation with signal amplification in a long-length Raman-amplifier fibre followed by a short-length parametric amplifier implemented on a separate highly nonlinear fibre. For the data rate 10 Gbps, the achievable gain ripple is as low as 1.9 dB, without any gain-compensation technique. The optical signal-to-noise ratio larger than 18 dB and the flat gain confirm that our Raman fibre-optic parametric amplifier can be used as a tunable and broad-gain amplifier for the future long-haul DWDM systems. The results obtained for our system have been compared with those of the L-band optical amplifiers developed recently. The comparison testifies that our amplifier is the best of all existing analogues.

“…We then describe the generation of a single channel 100 Gb/s signal. Several groups have proposed and demonstrated 100 Gb/s transmitters, such as using NRZ (Schuh et al, 2007), duo-binary (Winzer et al, 2005), and differential quadrature phase shift keying (DQPSK) (Daikoku et al, 2006) and serial dark-return-to-zero (SDRZ) (Ellis & Chow, 2006).

“…The 100 Gbit Ethernet (GbE) has already been considered as a next-generation network system. 1) Wavelength division multiplexing (WDM), time division multiplexing (TDM), 2) and differential quadrature phase shift keying (DQPSK) 3) are technology candidates for long-distance networks of over several tens of km. However, economical and scalable large-capacity optical link techniques are required for short-distance networks.…”

A 10 Gbps/channel 1 Â 10 vertical-cavity surface-emitting laser (VCSEL) array of 850 nm wavelength was demonstrated for a 100 Gbps (10 Gbps Â 10) local area network. The VCSEL array was oxidized using an in situ probing technique. The threshold current of each VCSEL on the array is approximately 0.5 mA with the oxide and metal apertures of 8 and 6 mm, respectively. The temperature characteristic of lasing from À40 to 120 C was stable and the f À3 dB cutoff frequency exceeded 10 GHz at 6 mA. The data transmission test through the conventional multimode fiber of 300 m length was carried out. We also investigated the reliability of the VCSEL array at an ambient temperature of 120 C and a dc current of 15 mA. We could achieve a failure rate over a decade below 1% at a temperature and current of 60 C and 7 mA, respectively.
