A novel high frequency, high bandwidth, three phase Mach-Zehnder optical data link

Area of Science:

• Nuclear Engineering
• Plasma Physics
• Optical Communications

Background:

• Inertial confinement fusion (ICF) requires precise measurement of fusion reaction history.
• Short experimental durations (60-150 ps) and high radiation environments pose significant diagnostic challenges.
• Existing methods struggle to balance dynamic range and time resolution for remote signal transmission.

Purpose of the Study:

• To develop and demonstrate a new optical data link for ICF diagnostics.
• To overcome limitations in signal transportation for fusion reaction history measurements.
• To maintain high dynamic range and 10 ps time resolution over long distances.

Main Methods:

• Introduction of a three-phase Mach-Zehnder modulator system.
• Design and construction of a physical prototype for the optical data link.
• Experimental testing of the system at the OMEGA facility.

Main Results:

• The optical data link successfully transported diagnostic signals over great distances.
• The system maintained the required dynamic range for signal measurement.
• Initial tests confirmed the viability of the proposed signal transportation method.

Conclusions:

• The developed optical data link is a viable solution for transmitting diagnostic signals in ICF.
• This technology enhances the capability to measure fusion reaction history with high fidelity.
• The system addresses critical diagnostic challenges in high-radiation, short-duration fusion experiments.
