Abstract: An optical source (100) comprising a supercontinuum generation apparatus comprising a pump light source (102), a twisted photonic crystal fibre, PCF, (104) and a wideband quarter-wave retarder (106). The pump light source is arranged to provide circularly polarised pump light. The twisted PCF is arranged to receive the pump light and to convert the pump light into circularly polarised supercontinuum light. The wideband quarter-wave retarder is arranged to convert the circularly polarised supercontinuum light into linearly polarised supercontinuum light. The optical source may additionally comprise a wavelength tunable bandpass optical filter arranged to transmit the linearly polarised supercontinuum light at wavelengths within a selected range.
