Summary
Spectroscopy is an important tool to understand molecular and atomic phenomena. Dual comb spectroscopy DCS and asynchronous optical sampling AOSPS are prominent techniques in infrared and Terahertz range respectively. Both rely on dual frequency combs or dual (FC), and their limitations stem from the comb design, necessitating a trade-off between speed and resolution. The spectral resolution is limited by the repetition rate of the FC. The most common sources for FC are mode-locked lasers and electro-optic modulators. However, due to technical peculiarities, these techniques are not suited for low repetition rates, leading most spectroscopy systems in the 100 MHz-10GHz range. TRESOR (Terahertz high resolution spectroscopy using driven optical resonators) aims to showcase a novel optical platform based on ultrashort pulses in low repetition rate, high-Q resonator, to address the limitations inherent in FC based spectroscopy methods. On the fundamental front, I will investigate the generation of novel soliton formations, such as super cavity solitons SCS in high intrinsic loss resonator with large detuning. So far, SCS in low repetition rate resonators have not been experimentally explored, mainly because of the lack of a sufficiently precise perturbation. To use the FC based on SCS in the THz range, pulses need to be amplified. This will give rise to a new challenge related to sub-200fs pulse amplification. On the applied side, by using FC based on SCS, TRESOR can improve the resolution and speed of current spectroscopy methods and give rise to new nonlinear measurement techniques. Despite these fundamental and applied reasons, the experimental approach of TRESOR will overcome such challenges and enable the realization of high-resolution spectroscopy in the THz range with performance beyond the state of art. This project is a step forward in my career because it will act as a springboard towards a permanent research position and will allow me to lead a research group
