Abstract:
The present invention includes a method for tuning the spectral response of a monolithic tapered (18) coaxial optical fibre filter (10) to have predetermined spectral characteristics. Thermal energy is applied at least to one spectrum-tuning portion of the monolithic tapered (18) coaxial optical fiber filter (10). The thermal energy produces a predetermined alteration of the spectral response of the monolithic coaxial tapered (18) optical fibre filter (10). The monolithic tapered (18) coaxial optical fiber filter (10) consists of a single-mode optical fibre (25) with concatenated tapered (18) coupling regions (300) designed to couple the fundamental fibre mode with the first higher order mode of the fibre (25) and corresponding phase shifting region (20, 21) between the tapered (18) coupling regions (300). Phase shifting regions (20, 21) and coupling regions (300) constitute the spectrum-tuning portions of the filter.
