We report on the design of a compact grism-pair stretcher for a near-infrared noncollinear optical parametric chirped-pulse amplification (OPCPA) system. The grisms are produced by bonding a grating to a prism using a resin. The stretcher is capable of controlling a bandwidth of over 300 nm, which is suitable for parametric amplification of few-cycle pulses. After amplification, pulses can be compressed by the dispersion of optical glass, and the residual group-delay can be compensated with an acousto-optic programmable dispersive filter (AOPDF).

This paper introduces a new nanoscale slot waveguide using organic material, graphene, and silicon-based materials. The physical mechanism of additional biased voltage can improve the performance of graphene-related waveguide, the proposed waveguide exhibits tunable performance including effective refractive index and dispersion without changing its structure and geometric dimension, which contributes to the practical value in future complex signal processing system. Based on the waveguide, wavelength conversion based on four-wave mixing is theoretically investigated in the near-infrared region and the tunable wavelength conversion is realized. These research results will have potential in the fields of data transmission and optical communications and help researchers deeply understand the physical mechanisms and nonlinear effects about the optical pulse generation processes and signal processing.

Attosecond Pulse Generation

A method for the carrier envelope phase (CEP) measurement of the multi-cycle mid-infrared field has been theoretically presented by using the CEP dependence of the harmonic cutoffs. It shows that by properly adding a CEP-known few-cycle near-infrared pulse to the multi-cycle mid-infrared field, the CEP dependence of the harmonic cutoffs from the combined field become much more distinct in comparison with those from the single mid-infrared field, which provides a route to a new CEP measurement technique. Further, by properly controlling the combined field, three supercontinua of 230, 242, and 266 eV with less modulation can be obtained. Finally, by selecting the generated harmonics, a series of sub-35 as pulses in the X-rays region can be produced.
