    Polarimetry improves spectral measurement of swept-wavelength sources

    Although optical-spectrum analysis and polarization measurement methods are not generally related, a collaborative effort by scientists at Tianjin University (Tianjin, China), General Photonics (Chino, CA), and the University of Southern California (Los Angeles, CA) has resulted in a polarimeter-based optical-spectrum analyzer (P-OSA) that measures with a speed and resolution that cannot be achieved using traditional grating-based, filter-based, or interferometric methods.1 In fact, the method w
