Abstract
High quality single-crystal GaSe nanoribbons (NRs) are fabricated and demonstrated as waveguides with good performance. By taking advantage of the strong confinement and long interaction length of the waveguiding approach, significantly enhanced nonlinear light–matter interaction is observed in GaSe NRs. Based on transverse SH generation, a single GaSe NR-configured optical auto-correlator is constructed for ultrashort pulse characterization. Because of the large second-order nonlinear susceptibility, high sensitivity with femto-joule-level pulse energy that has higher sensitivity than those reported before is demonstrated.
