Summary:•New method for fabrication of saturable absorbers for operation in ring fiber lasers is proposed.•The method combines the manufacturing technologies of fiber couplers and microfiber tapers coated with carbon nanotubes.•Fabricated saturable absorber enables generation of picosecond soliton pulses in ring fiber laser configuration. We report on a new method for fabrication of saturable absorbers for operation in ring fiber lasers as a mode-locking element taking advantages of the manufacturing technologies of fiber couplers and microfiber tapers coated with carbon nanotubes. It is demonstrated in the experiment that the transmittance of the fabricated saturable absorber increases with an increase of the input radiation power. Also, we have shown that the fabricated saturable absorber enables generation of picosecond soliton pulses in ring fiber laser configuration.
