    2. Soliton microcomb based spectral domain optical coherence tomography

      Soliton microcomb based spectral domain optical coherence tomography
      Spectral domain optical coherence tomography (OCT) is a widely employed, minimally invasive bio-medical imaging technique, which requires a broadband light source, typically implemented by super-luminescent diodes. Recent advances in soliton based photonic integrated frequency combs (soliton microcombs) have enabled the development of low-noise, broadband chipscale frequency comb sources, whose potential for OCT imaging has not yet been unexplored. Here, we explore the use of dissipative Kerr soliton microcombs in spectral ...

    4. Soliton microcomb based spectral domain optical coherence tomography

      Soliton microcomb based spectral domain optical coherence tomography
      Spectral domain optical coherence tomography (SD-OCT) has become a widely applied minimally invasive technique for bio-medical imaging[14], and industrial process control[5]. One of the most commonly used light source for SD-OCT is based on superluminescent diodes (SLD), which provide a low-noise broadband coverage.[6] Recent advances have allowed creating photonic integrated chipscale frequency combs, that provide an attractive alternative illumination scheme for SD-OCT. Yet to date, the use ...
