| Title: | Influence of strain and pressure to the effective refractive index of the fundamental mode of hollow-core photonic bandgap fibers | Authors: | Pang, M Xuan, H Ju, J Jin, W |
Issue Date: | 21-Jun-2010 | Source: | Optics express, 21 June 2010, v. 18, no. 13, p. 14041-14055 | Abstract: | We investigate the phase sensitivity of the fundamental mode of hollow-core photonic bandgap fibers to strain and acoustic pressure. A theoretical model is constructed to analyze the effect of axial strain and acoustic pressure on the effective refractive index of the fundamental mode. Simulation shows that, for the commercial HC-1550-02 fiber, the contribution of mode-index variation to the overall phase sensitivities to axial strain and acoustic pressure are respectively ~-2% and ~-17%. The calculated normalized phase-sensitivities of the HC-1550-02 fiber to strain and acoustic pressure are respectively 1 ε⁻¹ and −331.6 dB re μPa⁻¹ without considering mode-index variation, and 0.9797 ε⁻¹ and −333.1 dB re μPa⁻¹ when mode-index variation is included in the calculation. The latter matches better with the experimentally measured results. | Keywords: | Energy gap Fiber optic components Fibers Light refraction Organic polymers Pressure effects Refractive index Refractometers Sensitivity analysis Spontaneous emission |
