In this paper we will discuss avenues to exploit the potential low loss and low linearity of hollow core photonic band gap fibres (HC-PBGF) at 2 microns wavelength. In particular, we will show recent developments in semiconductor devices to enable a 100Gbit/s transmission demonstration.
In this paper, we will demonstrate the possibility of opening a new telecommunications transmission window around the 2 µm wavelength, in order to exploit the potential low loss of hollow-core photonic bandgap fibers, with the benefits of significantly lower non-linearity and latency. We will show recent efforts developing a dense wavelength division multiplexing testbed at this waveband, with 100...
Progress on advanced active and passive photonic components that are required for high-speed optical communications over hollow-core photonic bandgap fiber at wavelengths around 2 μm is described in this paper. Single-frequency lasers capable of operating at 10 Gb/s and covering a wide spectral range are realized. A comparison is made between waveguide and surface normal photodiodes with the latter...
This paper presents WDM transmission at 2μm over 1.15km of HC-PBGF with wavelength channels selected to span a 36.3nm waveband. A total capacity of 81Gbit/s was achieved using 4×12.5Gbit/s NRZ-OOK external modulation and 4×7.7Gbit/s 4-ASK Fast-OFDM direct modulation signals.
The TV evolution and the need of better quality and new services for the users have accelerated the migration from analogue to digital TV, forcing a renovation process in all fields of this communication system. Most of the DVB-T networks deployed in the world have been designed for fixed rooftop reception. The countries where it has not yet deployed the DTT network can introduce technological advances...
