Technique for Highly Sensitive Measurement of Raman Gain Coefficient of Optical Fiber using Pump/Signal Sum-Frequency Lock-In-Detection

Not Accessible

Your library or personal account may give you access

Abstract

A simple technique for measuring Raman gain in short optical fibers is demonstrated. This technique applies square-wave modulation to both pump and signal and performs lock-in-detection at sum-modulation-frequency, and measures on-off gain as small as 0.0015 dB.
