Periodic Reporting for period 1 - CSOC (Chip-scale Optical Atomic Clock)
Periodo di rendicontazione: 2022-10-01 al 2023-09-30
Realizing this ambitious endeavor presents a multitude of challenges. To begin, the development of a Silicon Nitride (SiN) platform capable of integrating III-V materials is imperative. The theoretical models and designs are needed for achieving an octave-spanning Kerr soliton comb. The creation of a comprehensive set of new processes is essential, including the fabrication of a GaAs quantum dot amplifier and an AlGaAs second harmonic generation (SHG) device. Furthermore, the miniaturization of the rubidium-based spectroscopy setup to chip-scale dimensions is a task that requires meticulous engineering. This consortium brings together the leading groups in Europe in the domain of Frequency combs, micro-comb technology, and photonic chipscale laser integration. Their collective expertise is instrumental in addressing these formidable challenges and advancing the frontiers of optical atomic clock technology.
