Abstract :
The application of microfibre couplers in a comb-filter-based ratiometric wavelength measurement system is discussed. The fabrication of microfibre coupler is presented and its temperature-dependent performance is investigated. The resolution of the ratiometric wavelength measurement system with a microfiber coupler is significantly improved in comparison with a conventional ratiometric system to better than 4 pm maintaining the potential for high measurement speed and wide measurable wavelength range.
