- 論文の詳細を見る
A novel servo control method has been developed to output a highly linear state of polarization (SOP) from a polarization-maintaining (PM) fiber. The correction signal is obtained using an SOP detection setup invented by Hänsch and Couillaud. This servo control method was then applied to fiber-component based frequency modulation spectroscopy experimentally to reduce the residual amplitude modulation (RAM) induced by nonlinear SOP incident to an electro-optic modulator. With active servo control, stable linear SOP output of PM fiber and pure frequency modulation lineshapes are obtained. Finally, long-term measurements of the dispersion background signal with feedback loop on and off are performed to evaluate the stability of RAM reduction.
