A chip-scale second-harmonic source via self-injection-locked all-optical poling [PDF]
Light: Science & Applications, 2023 We present a chip-scale second-harmonic source based on the self-injection-locking of a semiconductor laser to a high-Q silicon nitride microresonator. All-optical poling enables efficient frequency conversion with hertz-level emission linewidth.

Study on the Estimation of Utility Harmonic Impedance Based on Minimum Norm of Impedance Difference
IEEE Access, 2020 The existing methods for estimating harmonic impedance usually assume that harmonic impedance is constant in a measurement period. However, for a variety of practical reasons, such as the load change of power grid, utility harmonic impedance may be ...

Breakdown of the mirror image symmetry in the optical absorption/emission spectra of oligo(para-phenylene)s [PDF]
, 2005 The absorption and emission spectra of most luminescent, pi-conjugated, organic molecules are the mirror image of each other. In some cases, however, this symmetry is severely broken.

Internal kinematics of spiral galaxies in distant clusters IV. Gas kinematics of spiral galaxies in intermediate redshift clusters and in the field [PDF]
, 2010 (Abridged) We trace the interaction processes of galaxies at intermediate redshift by measuring the irregularity of their ionized gas kinematics, and investigate these irregularities as a function of the environment (cluster versus field) and of ...
