Abstract
In this summary, a fully akinetic FDML-like or so-called dual resonance sweeping regime, for swept source optical coherence tomography, SS-OCT, at 1550 nm is demonstrated. Instead of modulating the optical amplifier gain reported in our previous studies, here we employ a fiber intensity modulator as a mode-locking element. A chirped fiber Bragg grating is used to provide sufficient dispersion in the laser cavity. A tuning range of 25 nm is obtained for a sweep frequency of ≈ 900 kHz with a 6 dB drop-off in sensitivity at 2.6 mm optical path difference. Similarities in operation with the FDML concept are presented.
