We demonstrate a high-speed wavelength-swept laser with a tuning range of $104\mathrm{nm}$ ( $1228–1332\mathrm{nm}$ ) and a repetition rate of $403\mathrm{kHz}$ . 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 $98\mathrm{dB}$ with single-side ranging depth of $1.7\mathrm{mm}$ over $4\mathrm{dB}$ sensitivity roll-off.
