Characteristics of mismatched twin-core fibre spectral filters

Characteristics of mismatched twin-core fibre spectral filters
Characteristics of mismatched twin-core fibre spectral filters
Both bandstop and bandpass filters can be easily implemented with mismatched twin-core fibres designed to phase-match at certain wavelength. These filters are highly stable with very low temperature and strain sensitivity. We studied the spectral quality of these filters and that of cascaded filters designed to achieve improved bandpass response. We have also demonstrated the feasibility of achieving designed loss profile from these filters. This is very useful in gain spectrum flattening in Er-doped fibre amplifiers.

Abstract

Both bandstop and bandpass filters can be easily implemented with mismatched twin-core fibres designed to phase-match at certain wavelength. These filters are highly stable with very low temperature and strain sensitivity. We studied the spectral quality of these filters and that of cascaded filters designed to achieve improved bandpass response. We have also demonstrated the feasibility of achieving designed loss profile from these filters. This is very useful in gain spectrum flattening in Er-doped fibre amplifiers.
