Timing Distribution optical communication
Ultra-stable distribution of timing signals is of high importance in academic research infrastructures such as particle accelerators. The requirements of future accelerators for stable timing are expected to increase substantially. Newest generation high brightness ultrafast x-ray sources driven by free electron lasers have typically sub-10 fs requirements on the distribution of RF signals to accelerator components and laser systems.
In general, optical clock distribution and synchronization will become more important in future. Technologies and applications such as ultraprecise navigation, gravitational sensing, coherent arrays or relativity experiments will require time comparison and synchronization over terrestrial fiber-optic links or satellite free-space links.

Menhir Photonics added values
Menhir Photonics offers modelocked lasers with the lowest phase-noise available on the market today combined with extreme reliability. The graph/figure below shows a typical phase noise measurement for a free-running laser of the MENHIR-1550 series, measured on the 10 GHz carrier i.e. the 40th harmonics (250 MHz pulse repetition rate). Note that the noise floor of the measurement limits the integrated timing jitter to approximately 500 as (attoseconds).

Integrated timing jitter starting at 10 MHz for the same free-running laser.
All lasers of the MENHIR-1550 SERIES have an optional fast repetition rate tuning with a modulation bandwidth of >50 kHz for repetition rate locking or synchronization. In addition, there is also the option for fast modulation of the pump current.
The MENHIR-1550 SERIES reaches unmatched levels of industrial quality and environmental stability. It has been excessively tested for vibrations, shocks and other external disturbances (space and aerospace related standard tests). For integration into space-critical applications, customized small-sized versions are available.
