We propose and experimentally demonstrate a photonic-assist measurement of microwave frequency by utilizing two cascaded photonic crystal (PC) cavities. By injecting different powers into the PC cavities, the device transmission spectra could be effectively manipulated. Consequently, the central fre...

We propose and experimentally demonstrate an all-optical switch based on a fiber-chip-fiber opto-mechanical system driven by thermal radiation. The two optical fibers are both designed as movable cantilever structures with a free-hanging length. With injecting pump lights into the opto-mechanical sy...

IntroductionThis study investigates how paternalistic leadership (authoritarian, benevolent, and moral) affects counterproductive work behavior among Chinese Generation Z employees. By integrating culturally specific leadership styles with generational traits, this research offers insights into the...

BackgroundNon-small cell lung cancer harboring EGFR mutations is responsive to targeted therapies such as Osimertinib. Although metastasis from lung cancer to the prostate is exceedingly rare, we present a rare case of prostatic metastasis from lung adenocarcinoma in a patient with a history of hepa...

We propose and experimentally demonstrate photonic measurement of microwave frequency by utilizing an optomechanical microring resonator (MRR). The pump powers injected into the MRR would result the resonance red-shifts based on nonlinear effects. In the case of optical single sideband modulation, t...

Acute minor ischemic stroke (AMIS) patients may experience unfavorable outcomes despite mild initial symptoms. The ratio of red blood cell distribution width (RDW) to albumin (ALB) (RAR) has been associated with poor outcomes after stroke, but its role in AMIS remains unclear. This study aimed to in...

By utilizing two cascaded all-silicon opto-mechanical microring resonators (MRRs), an energy-efficient optical diode with high nonreciprocal transmission ratios (NTRs) is proposed and experimentally realized. The optical diode is composed of an all-pass opto-mechanical MRR and an add-drop opto-mecha...
