Regeneration station

Architecture

This equipment is a stand-alone device that enables to coherently regenerate an optical signal allowing long-haul dissemination of an ultra-stable optical frequency reference. Its architecture is based on the heterodyne phase-locking of a narrow spectral width laser diode on the reference signal. The station is equipped with low phase noise optical interferometer that perform a thorough characterization of the phase noise accumulated by the incoming signal, and a compensation system of this phase noise.
