Multi-Point Optical Vector Analyzer Based on Optical Linear Frequency-Modulated Waveform and Kramers-Kronig Receiver

A multi-point OVA is proposed based on optical linear frequency-modulated waveform and Kramers-Kronig receiver, which can be applied in multiple optical devices measurement. In the experiment, a PS-FBG and a fiber-based MZI are measured simultaneously, where the spurious signals in the photocurrent are suppressed close to the noise floor through using Kramers-Kronig receiver and the measurement accuracy is largely enhanced.
