Cryogenic microwave and optical resonators
Giuseppe graduated from the Politecnico di Torino (Italy) in 2000 and joined NPL in 2002. His background is mainly in the areas of microwave frequency synthesis, phase noise and frequency stability measurements. His research at NPL has included the development of high stability microwave cryogenic sapphire oscillators, ultra-low phase noise frequency chains for the atomic fountain primary frequency standards and a high accuracy laser tracker interferometer system.
Giuseppe’s current research activities include low noise microwave synthesis and transfer of frequency stability around the optical region of the spectrum, by operation of femtosecond combs (link to “femtosecond combs”) in optical clock mode (link to “frequency measurements and optical clocks”). He is also working on techniques for dissemination of optical frequencies (link to “comparison of optical frequency standards”) and short pulses through optical fibre networks.
Giuseppe is a member of the IEEE.
