Abstract :
We demonstrate an ultra-wideband light source using multi-wavelength single-sideband modulation (SSB) frequency sweep technique, aiming at optical coherence tomography (OCT). The light source consists of an optical SSB frequency sweeper with an optical frequency comb generator cascaded with a multi-wavelength laser. Ultra-wideband signal was generated by sweeping frequency of each components of an optical multi-wavelength light source. The proposed system can achieve much faster and more precise spectrum measurement than the conventional OCT system.
