Self‐Detecting Mid‐Infrared Dual‐Comb Spectroscopy Based on High‐Speed Injection‐Locked Quantum Cascade Lasers

open access: yesAdvanced Photonics Research, EarlyView.
A compact self‐detecting dual‐comb spectroscopy (DCS) system based on dispersion‐engineered, high‐speed packaged quantum cascade lasers (QCLs) at λ≈4.6 μm under coherent injection locking is demonstrated. Broad multiheterodyne comb signal with reduced tooth linewidths by orders of magnitude is recorded.

Blue‐to‐Green Fine‐Tunable Narrowband Delayed Fluorescence in Peripherally Dendritic Modified Bis‐Indolocarbazoles

open access: yesAngewandte Chemie, EarlyView.
An exquisite color tuning of narrowband thermally activated delayed fluorescence from deep‐blue to green was achieved for non‐boron ubiquitous luminophores based on the dendritic modification design concept. The corresponding OLEDs exhibited high‐efficiency, high‐color‐purity blue and green electroluminescence, with high external quantum efficiencies ...

Topological Berry Antenna on a Silicon Chip for Terahertz Wireless Communication

open access: yesAdvanced Photonics Research, EarlyView.
The on‐chip topological Berry antenna for 6G to Xth‐generation wireless communication is designed via integrating various Berry curvatures for an enhanced antenna aperture and radiation gain. This THz antenna has demonstrated a maximum gain of 17 dBi and chip‐to‐chip wireless communications at 20 Gbps over a distance of 15 cm.

Azuperylene: The Nonalternant Isomer of Perylene

open access: yesAngewandte Chemie, EarlyView.
As a nonalternating isomer of perylene, azuperylene (AP) is formed by the C─H/C─I coupling reactions we developed at the 1,8‐positions of azulene. The aromatic characteristics of the initial azulene are retained, and side chain modifications regulate the stacking pattern. The core of AP has smaller mutual perturbation compared to perylene.

Universal and deterministic manipulation of the quantum state of harmonic oscillators: a route to unitary gates for Fock State qubits

open access: yes, 2004
We present a simple quantum circuit that allows for the universal and deterministic manipulation of the quantum state of confined harmonic oscillators. The scheme is based on the selective interactions of the referred oscillator with an auxiliary three ...

Analysis of Electronic Structure and Binding Energy in Five‐Electron GaAs/AlxGa1‐xAs Quantum Dots Under Penetrable Confinement Potential

open access: yesAdvanced Theory and Simulations, EarlyView.
This study analyses the electronic structure of five‐electron spherical quantum dots with penetrable confinement potential. Spatial confinement and the influence of potential barrier height give rise to the unique properties of quantum dots. These effects lead to profound changes in their energy spectra and optical properties which play a key role in ...

A Sub‐Diffraction‐Limit Dimension All‐Plasmonic Optical Memory Using Non‐Linear Photochromism

open access: yesAdvanced Science, EarlyView.
An all‐plasmonic optical memory is demonstrated by using nonlinear plasmonics on a sub‐diffraction limit plasmonic nanowire waveguide coated with a photochromic diarylethene that supports the complete memory processes, “Write”, “Erase”, and “Readout” the memory ON/OFF states. Abstract The development of compact, high‐speed, and energy‐efficient optical

Wavefunctios of log-periodic oscillators

open access: yes, 2011
We use the Lewis and Riesenfeld invariant method [\textit{J. Math. Phys.} \textbf{10}, 1458 (1969)] and a unitary transformation to obtain the exact Schr\"{o}dinger wave functions for time-dependent harmonic oscillators exhibiting log-periodic-type ...
