摘要：
A semiconductor source spectroscopy system controls optical power variation of the tunable signal due to polarization dependent loss in the system and thus improves the noise performance of the system. It relies on using polarization control between the source and the sample and/or the sample and the detector. In one example, the source has a semiconductor optical amplifier and an intracavity tunable element for generating a tunable optical signal for illuminating a sample. The tunable optical signal is spectrally tuned over a scan band of the spectroscopy system by operation of the intracavity tunable element.
