Abstract

In this paper, the application of a broadband spatially coherent IR supercontinuum source to the biomedical imaging and detection is presented. New IR material is proposed to generate Mid-IR supercontinuum above 4um, which was previously difficult due to inherent material absorption. Broad Mid-IR supercontinuum is numerically shown to be possible with one single wavelength pump in appropriate fiber structure. Mid-IR broadband sources are very useful in IR Optical Coherence Tomography (OCT) and spectroscopy in biomedical materials, due to the rich absorption structures the Mid-IR region. Broadband Mid-IR source is better than single wavelength tunable source, such as Quantum Cascaded Lasers (QCL), for faster analysis speed, since slow scan is not required.
