Wavelength Tunable Fiber Laser Technology for Optical Coherence Tomography

Wavelength tunable laser has always been the key technology for wavelength-division multiplexing optical communication community, but few have realized that wavelength-swept laser has great potentials in biomedical applications. In this talk, the application of wavelength-swept fiber laser will be especially discussed for Fourier-domain optical coherence tomography source. Various wavelength-swept lasers are investigated using novel fiber-optic wavelength-selecting filters, such as polarization-maintaining fiber and acousto-optic Sagnac loop tunable filters.
