Frequency Stability Transfer Over a Wide Spectral Band Using Fibered Bragg Grating Cavities

Transferring the stability characteristics of an optical frequency reference towards another application wavelength is a major issue for laser metrology. This involves transferring both frequency stability and spectral purity [1]. Many applications require those characteristics such as high-resolution spectroscopy, instrument synchronization, ultra-sensitive coherent detection for high-capacity telecommunications or coherent manipulation of quantum states in atomic systems (atomic clocks, single-photon sources and qbits). For this purpose, frequency combs are commonly used in metrology laboratories.
