Abstract
We demonstrate a high-speed wavelength-swept laser with a tuning range of () and a repetition rate of . The design of the laser utilizes a high-finesse polygon-based wavelength-scanning filter and a short-length unidirectional ring resonator. Optical frequency domain imaging of the human skin in vivo is presented using this laser, and the system shows sensitivity of higher than with single-side ranging depth of over sensitivity roll-off.
