Monolithic Integration of Mid-Infrared Quantum Cascade Lasers and Frequency Combs with Passive Waveguides
Ruijun Wang, Philipp Täschler, Zhixin Wang +3
Mid-infrared semiconductor lasers in photonic integrated circuits are of considerable interest for a variety of industrial, environmental, and medical applications. However, photon…
Ultra-low threshold lasing through phase front engineering via a metallic circular aperture
Zhixin Wang, Filippos Kapsalidis, Ruijun Wang +2
Semiconductor lasers with ultra-low thresholds and minimal footprints are a topic of active research. Such devices require a combination of high quality factor laser cavities with…
Topological charge of finite-size photonic crystal modes
Zhixin Wang, Yong Liang, Mattias Beck +2
Topological charges are the winding numbers of polarization vectors around the vortex centers of far-field radiation. In this work, the topological charge of photonic crystal modes…
A Changing Dichotomy: The Conception of the "Macroscopic" and "Microscopic" Worlds in the History of Physics
Zhixin Wang
This short essay traces the conceptual history of micro- and macroscopicity in the context of physical science. By focusing on three distinct episodes spanning five centuries, we s…
Superradiantly limited linewidth in complementary THz metamaterials on Si-membranes
Janine Keller, Johannes Haase, Felice Appugliese +6
We study complementary double split ring THz resonators fabricated on a 10 mum thin Si-membrane. The linewidths of the fundamental LC-mode and dipolar mode are drastically narrowin…
Quantum Microwave Radiometry with a Superconducting Qubit
Zhixin Wang, Mingrui Xu, Xu Han +6
The interaction of photons and coherent quantum systems can be employed to detect electromagnetic radiation with remarkable sensitivity. We introduce a quantum radiometer based on…
Heralded Generation and Detection of Entangled Microwave--Optical Photon Pairs
Changchun Zhong, Zhixin Wang, Changling Zou +8
Quantum state transfer between microwave and optical frequencies is essential for connecting superconducting quantum circuits to coherent optical systems and extending microwave qu…
Analytical study of mode degeneracy in non-Hermitian photonic crystals with TM-like polarization
Xuefan Yin, Yong Liang, Liangfu Ni +3
We present an analytical study of the mode degeneracy in non-Hermitian photonic crystals (PC) with symmetry, from the perspective of the coupled-wave-theory (CWT). The wav…
Analytical coupled-wave model for photonic crystal quantum cascade lasers
Zhixin Wang, Yong Liang, Xuefan Yin +3
A coupled-wave model is developed for photonic-crystal quantum cascade lasers. The analytical model provides an efficient analysis of full three-dimensional large-area device struc…
Quantum Simulation of Pairing Hamiltonians with Nearest-Neighbor Interacting Qubits
Zhixin Wang, Xiu Gu, Lian-Ao Wu +1
Although a universal quantum computer is still far from reach, the tremendous advances in controllable quantum devices, in particular with solid-state systems, make it possible to…
Phonon amplification in two coupled cavities containing one mechanical resonator
Hui Wang, Zhixin Wang, Jing Zhang +3
We study a general theory of phonon lasing [I. S. Grudinin et al., Phys. Rev. Lett. 104, 083901 (2010)] in coupled optomechancial systems. We derive the dynamical equation of the p…
