Parallel broadband fluorescent light source for optical coherence tomography

We present a new light source for parallel Optical Coherence Tomography (OCT) based on multiple waveguides written in Ti:sapphire. Each channel can generate a spectrum of 174 nm bandwidth centered at 772 nm, with an optical power on sample of 30 mu W. A system depth resolution of 1.9 mu m is obtained, which correspond to 1.5 mu m in tissue.
