title: 2.2 microm axial resolution optical coherence tomography based on a 400 nm-bandwidth superluminescent diode.
abstract: We demonstrate 2.2 microm axial resolution optical coherence tomography (OCT) in 1.1-1.7 microm wavelength regime by using a nonidentical multiple-quantum-well (MQW) superluminescent diode (SLD) with record-bandwidth emission. The compact, low-cost, and reliable light source with extreme broadband emission demonstrates significant potentials for spectroscopic and commercial OCT applications requiring ultrahigh spatial resolution.
