Unbalanced Orthogonal Polarization Interrogated Optical Vector Analysis

Interferometric optical vector analysis (OVA) technique, employing orthogonal polarization interrogation and polarization diversity detection, provides comprehensive spectral response characterization of optical devices, though with exacting polarization alignment demands. To overcome this intrinsic limitation, we introduce an unbalanced orthogonal polarization-interrogated OVA scheme that operates without active polarization control. Besides, our method achieves performance parity with leading commercial instrument.
