Transfer-Printed Photonic Crystal Nanobeam Laser With Unidirectional Coupling…
We propose and study the hybrid integration of a 1D photonic crystal (PhC) nanobeam (NB) laser on a SiN x waveguide. With modifications by reduced-PhCs and a tapered beam to the NB laser, this inte…
High-Speed 9.6-μm Long-Wave Infrared Free-Space Transmission With a Directly…
Free-space optics (FSO) in the mid-infrared (mid-IR) contains rich spectral resources for future ultrahigh-speed wireless communications yet is currently under-exploited. Two atmospheric transmissi…
Lithium Niobate Thin Film Polarization Beam Splitter Based on Asymmetric Dire…
Polarization devices on lithium niobate thin film (LNTF) are vital components for photonic integrated circuits (PICs) on the novel platform. Because both linear and nonlinear devices on the anisotr…
Power Sparse Code Division Non-Orthogonal Multiple Access Scheme for Next-Gen…
In this paper, a power sparse code division non-orthogonal multiple access (PSCD-NOMA) scheme is proposed for next-generation flexible optical access, which is based on the multi-stack network. All…
Performance-Enhanced Optical Non-Orthogonal Multiple Access Enabled by Orthog…
In this paper, we propose a novel optical non-orthogonal multiple access (NOMA) scheme based on orthogonal chirp division multiplexing (OCDM) in a low-cost intensity modulation and direct detection…
High-precision Microwave Frequency Measurement Based on Stimulated Brillouin …
We propose and implement a microwave frequency measurement (MFM) scheme based on stimulated Brillouin scattering (SBS) and an apodized fiber Bragg grating (AFBG), achieving high accuracy in a wide …
Social Media Marketing, Quality Signaling, and the Goldilocks Principle
Embraced by a rapidly increasing number of companies, social media marketing has become an integral part of companies’ business strategies. However, not all the firms plan on a big spend on socia…
Optimization and Application of TiO2 Hollow Microsphere Modified Scattering L…
In our study, the dye-sensitized solar cells (DSSCs) with double-layer thin films were fabricated. The active bottom layer of the structure was mainly made of the commercially available titanium di…
Direct Modulation and Free-Space Transmissions of up to 6 Gbps Multilevel Sig…
A roadmap for future wireless communications is expected to exploit all transmission-suitable spectrum bands, from the microwave to the optical frequencies, to support orders of magnitude faster da…
Fast-Response Sensitivity-Enhanced All-Fiber Fabry–Pérot High-Pressure Sen…
A novel fast-response sensitivity-enhanced high-temperature all-fiber Fabry–Pérot high-pressure sensor formed with a hard-core diaphragm is proposed and demonstrated. The structure can effective…
