Abstract

This paper describes some aspects of the fluoride fibre optical transmission system experiments in progress at British Telecom Research Laboratories (UK). Initially, midinfra-red receiver designs based on InAs photovoltaic detectors are described . Preliminary measurments made at 1.52 μm indicate a sensitivity of -31.2 dBm with 34 MBit/s, non-return-to-zero, pseudo-random binary data. This is believed to be the first error-ratio characterization of an optical receiver with high responsivity in the 2-4 μm wavelength region. Further work will allow a complete mid-infra-red transmission system to be constructed. The initial design will use Zirconium Tetrafluoride fibre produced at BTRL and an optical source based on a 3.39 μm HeNe laser externally-modulated by a Ge Bragg cell. Results obtained at 34 MBit/s will be reported at the conference.
