We demonstrate ultrahigh resolution optical coherence tomography using continuum generation in an air-silica microstructure fiber. A broadband OCT system was developed, supporting a bandwidth of 370 nm at 1.3 μm center wavelength. We achieved longitudinal resolutions of 2.6 μm in air, or ∼2 μm in tissue. To our knowledge this is the highest longitudinal OCT resolution demonstrated in this wavelength range and the first application of this new light source for OCT. We also describe the application of this technique for imaging biological tissue in vivo.
