High Temperature Resistance of Polarization Maintaining Fiber for Campus Network Use
We report a periodic thermal cycling method to investigate the dynamic response of the polarization of a laser propagating through polarization-maintaining (PM) optical fiber, driven by periodic weak temperature modulation. INSTITUTIONAL Select your institution to access the SPIE Digital Library. It provides an expert-curated supplier directory, buyer-focused technical background information, and structured selection criteria to support professional procurement decisions. What are. Optical fiber transmits data via light pulses through a glass or plastic core, and its performance is highly dependent on environmental conditions—temperature being one of the most impactful. A var-iation of the Stokes parameters induced by the phase shift is expressed by the Jones matrix and a. A fiber ring resonator (FRR) constructed using a Panda polarization-maintaining fiber does not effectively solve the problem of temperature-related polarization fluctuation, which considerably limits the detection accuracy of the resonant fiber optic gyro. The polarization-maintaining photonic. -
