Abstract

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