Single-scan polarization-resolved heterodyne optical network analyzer
Conference on Optical Fiber Communication, Technical Digest Series | Published : 2002
A novel interferometric method for device characterization was presented. Reflectivity, transmissivity, group delay, chromatic dispersion (CD), polarization mode dispersion (PMD) and polarization dependent loss (PDL) was measured in one scan. The polarization-delay unit (PDU) splitted the light from the tunable laser source (TLS) into two lightwaves. The interferometric nature of the measurement enabled the dynamic range and wavelength resolution.
