Paper Abstract

Following a program funded by the European Space Agency, a novel laser-diode module has been created and tested to ESCC-23201-compliant space standards. Manufactured by Gooch & Housego, the module is set for imminent entry to the European space market for use in optical signal-processing and telecom systems. Emission is from a 1550nm DFB semiconductor laser diode driven at constant nominal current and temperature. Combined with a wavelength stability of better than ±0.1nm and internal data rate of up to 3.2GHz, innovative sub-design and packaging provides for a unique power capability comprising a start-of-life ex-fibre power of >90mW and a typical electric power consumption that, at <4.1W, is down to 25% of that of similar products. Validation testing by AdvEOTec (France) indicates a comprehensive set of space compliances such as in proton irradiation, humidity, hot/cold storage, rapid depressurisation, vibration and 1,000g shock, as well as immunity to ±8kV of ESD, 10-5mbar of vacuum, and 100krad of gamma irradiation. Unique methodologies for life-test modelling and production screening, established by Thales Alenia Space (France), provisionally confirm a 15-year space-compliant operating life. Space-compliant product, as presented, is intended to be supplied for a period of at least 5 years.
