Photonic bandgap crystals can reflect light for any direction of propagation in specific
wavelength ranges,,. This property, which can be used to confine, manipulate and guide …

Electrostatic coupling between particles is important in many microscopic phenomena found
in nature. The interaction between two isolated point charges is described by the bare …

Optical orientation of spin-polarized heavy and light holes followed by relaxation to other
valence subband states has been observed unambiguously in undoped bulk GaAs in spite …

摘要飞秒激光微加工技术具有加工精度高, 热效应小, 损伤阈值低以及能够实现真正的三维微

An experimental setup of three coupled PT-symmetric waveguides showing the
characteristics of a third-order exceptional point (EP3) has been investigated by Heiss and …

In this work, using finite-difference time-domain method, we propose and numerically
demonstrate a novel way to achieve electromagnetically induced transparency (EIT) …

The interaction of femtosecond and nanosecond laser pulses with the surface of glass was
compared. The glass was placed inside a vacuum chamber. The laser pulses were focused …

Recent success in the fabrication of axial and radial core–shell heterostructures, composed
of one or more layers with different properties, on semiconductor nanowires (NWs) has …

Time-resolved terahertz experiments in a novel setup were used for a direct observation of
the competition between the single-and two-photon absorption in highly excited GaAs. The …

Semiconductors play a crucial role in various industries, and the study of carrier dynamics is
essential in understanding their behavior. This manuscript presents the transient dynamics …
