“…High output power is allowed by the high optical gain in a semiconductor gain medium and its wide optical bandwidth. By combining outputs from several SLDs, the optical spectrum of the light source can be greatly extended [3–6].…”

“…This wavelength region benefits from the relatively large imaging depth of the OCT scans and the reduced costs of the fibre-optic components due to the well-established O-band optical telecommunication infrastructure [1,2]. Broad optical spectra are desired for OCT systems, because the axial imaging resolution is inversely proportional to the bandwidth of the light source [3,4].…”

A broadband light source that is based on a combination of three spectrally matched superluminescent diodes is demonstrated. The mean wavelength of the source is 1330 nm. The 3 dB spectrum width exceeds 180 nm and the 10 dB spectrum width is 220 nm. The spectral flatness is better than 2 dB and the residual spectral modulation is <0.5 dB for the whole spectral bandwidth of the source. The optical power coupled in a single-mode fibre is 4 mW.
