Precise Spectral and Impulse Response Characterization of Broadband Super Structured FBGs by Multi-Scan OSSB
Precise Spectral Impulse Response Characterization FBGs Multi-Scan OSSB
2015/5/15
We demonstrate a broadband optical single side band (OSSB) measurement by merging multiple RF scans. We provide a chip by chip optical phase measurements on a Super Structured FBG designed for Coheren...
Hybrid technique based on chirp effect and phase shifts for spectral Talbot effect in sampled fiber Bragg gratings (FBGs)
fiber Bragg gratings Talbot effect dispersion optical fiber communication
2011/5/5
To implement the spectral Talbot effect in sampled fiber Bragg gratings (SFBGs), a hybrid
technique based on a chirp effect and phase shifts is proposed. Firstly, the general phase condition
is deri...
