| Research Abstract |
We proposed and demonstrated a linear time-to-space mapping system, which was based on two times electrooptic sinusoidal beam deflection. The proof-of-concept experiments were carried out and the temporal resolution of 5 ps was demonstrated using traveling-wave type quasi-velosity-matched elec-trooptic beam deflectors. We also demonstrated the generation of an optical frequency comb with a Gaussian spectrum using a continuous-wave laser, based on spatial convolution of a slit and a periodically moving optical beam spot in a linear time-to-space mapping system. In a proof-of-concept experiment, a 16.25-GHz-spaced, 240-GHz-wide Gaussian-envelope OFC (corresponding to 1.8 ps Gaussian pulse generation) was demonstrated.
