A compact coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna with a band-notched performance is presented in this paper. The band-notched UWB antenna is designed on a 26×34×1.6 mm3 substrate. It consists of a circle ring with a T-shape constru
A compact and easy fabricated ultra-wideband antenna is proposed in this paper. It comprised of.a monopole antenna and a single-side I-shaped structure (ISS) metamaterial (MM) cladding. The monopole.itself resonates at 2.4 GHz and presents capacitive
Heterogeneously integrated lasers in the O-band are a key component in realizing low-power optical interconnects for data centers and high-performance computing. Quantum-dot-based materials have been particularly appealing for light generation due to
We report the experimental generation of narrow-band paired photons through electromagnetically induced transparency and spontaneous four-wave mixing in a two-dimensional magneto-optical trap (2D MOT). By controlling the optical depth of the 2D MOT f
Based on the triangular lattice two-dimensional photonic crystal (PC), the lattice spacing along the transverse direction to propagation is altered, and a gradient PC (GPC) flat lens is designed. The band structures and equal frequency curves of the
A narrow-linewidth laser operating at the telecommunications band combined with both fast and wide-band tuning features will have promising applications. Here we demonstrate a single-mode (both transverse and longitudinal mode) continuous microlaser
This paper proposes a subcarrier weighting technique to suppress the out-of-band radiation of OFDM signals. By mapping and weighting the same data on an adjacent pair of subcarriers, the spectrum sidelobes are suppressed perfectly through sidelobes m
