Resumo(s)

We report experimental evidence of improving the nonlinearity of conventional wavelength swept laser sources based on a fiber Fabry–Pérot tunable filter as a wavelength-selective element. Our solution is based on applying a nonsinusoidal, synthesized waveform to the tunable filter that can be identified experimentally. A significant improvement in the optical coher- ence tomography image quality has been obtained without any software recalibration method.
