A comprehensive study of the optical single-sideband (OSSB) modulation based optical vector network analyzer (OVNA) is performed to reveal the origination of the measurement error. By applying stimulated Brillouin scattering (SBS) in an 8-km single-mode fiber (SMF) as the device-under-test (DUT), and employing an optical processor to control the high-order sidebands of the OSSB signal, numerical simulation...
Optical vector network analyzer (OVNA) based on optical single-sideband (OSSB) modulation can measure phase and magnitude responses of an optical device with sub-MHz resolution. To reduce the measurement error caused by the high-order sidebands in the OSSB modulation schemes, a theoretical analysis is performed and an OSSB modulation scheme based on 120-degree hybrid coupler is proposed. A novel OVNA...
