Peculiarities of thermo-optic coefficient under different temperature regimes in optical fibers containing fiber Bragg gratings
Grigory Adamovsky,Sergei F. Lyuksyutov,Jeffrey R. Mackey,Bertram Floyd,Ujitha Abeywickrema,Igor Fedin,Mindaugas Rackaitis +6 more
TL;DR: In this paper, the diffraction efficiency of a fused silica fiber containing fiber Bragg gratings (FBGs) was found to fluctuate with temperature between 2.01 −10 − 4 and 0.17 − 10 − 4 with sub-Angstrom precision.
Proceedings ArticleDOI
Performance Evaluation of Fiber Bragg Gratings at Elevated Temperatures
TL;DR: In this article, the performance of fiber Bragg gratings at elevated temperatures was evaluated and various parameters of the fiber gratings were monitored and recorded, including peak Bragg wavelength, the power of the Bragg wavelengths, and total power returned by the fiber grating.
Proceedings ArticleDOI
Thermal Evaluation of Fiber Bragg Gratings at Extreme Temperatures
Jeffrey R. Juergens,Grigory Adamovsky,Ramakrishna T. Bhatt,Gregory N. Morscher,Bertram Floyd +4 more
TL;DR: In this paper, the performance of freestanding fiber Bragg gratings (FBG) at extreme temperatures was evaluated and various parameters of the FBGs performance were monitored and recorded.
Proceedings ArticleDOI
Single-mode fiber and few-mode fiber photonic lanterns performance evaluated for use in a scalable real-time photon counting ground receiver
Sarah A. Tedder,Brian E. Vyhnalek,Sergio G. Leon-Saval,Christopher H. Betters,Bertram Floyd,Jeremy Staffa,R. Lafon +6 more
TL;DR: In this article, the authors explore the use of photonic lanterns in a real-time ground receiver that is scalable and constructed with commercial parts, and show that the few-mode fiber lantern has higher coupling efficiency for telescopes with longer focal lengths under higher turbulent conditions.
Proceedings ArticleDOI
Measurements of few-mode fiber photonic lanterns in emulated atmospheric conditions for a low earth orbit space to ground optical communication receiver application
Sarah A. Tedder,Bertram Floyd,Yousef K. Chahine,Benjamin Croop,Brian E. Vyhnalek,Christopher H. Betters,Sergio G. Leon-Saval +6 more
TL;DR: In this article, a comparison of the throughput coupling loss at emulated atmospheric conditions for the case of a 60 cm diameter telescope receiving light from a low earth orbit satellite is presented.
