Phase Shift Measurement in DFB-LD Sensors by Marco Sotelo is a document available to read on EtoBox.

This paper presents a novel method for measuring the phase shift (φm) between central optical-frequency modulation (COFM) and accompanied optical-intensity modulation (AOIM) in distributed feedback laser diodes (DFB-LD) for fiber-optic sensor systems. The measurement technique utilizes an orthogonal test and does not require additional fiber etalons or high-speed demodulators, making it cost-effective. The study also analyzes the impact of φm on phase-generated carrier (PGC) demodulation results, providing
