The effects of doping in the multiquantum well (MQW) active region on the properties of InP-based long wavelength deep ridge transistor lasers (TLs) are numerically studied. Doping in the MQWs is shown to lead to a decrease of the slope efficiency and a notable increase of the current gain of the TL...

In this paper, we propose a channel load sensing protocol (CLSP) to prevent the throughput decrease at heavy traffic conditions in asynchronous optical code-division multiple-access (CDMA) networks. The multiple access-interference (MAI) and beat noise are considered the main deleterious source of t...

Recent extensive studies have promoted the imaging techniques through scattering layers to a reality but the imaging quality still needs to be improved. We demonstrate a high-speed method to image objects hidden behind a thin scattering medium. By analyzing the imaging degradation model of the speck...

We propose an effective scheme to enhance the efficiency of optical second-order sideband (OSS) via optomechanically induced absorption (OMIA) in a double-cavity optomechanical system. In this double-cavity optomechanical configuration, the optomechanical cavity is driven by a strong control field a...

The filtering and polarizing of terahertz waves are essential for various terahertz applications. Here, we use two-dimensional (2-D) rectangular subwavelength hole arrays (SHAs) to achieve efficient wave filtering and polarizing in the terahertz region. The transmissive filtering is obtained by exci...

This paper investigates the joint spectrum and energy efficiency in multimanned aerial vehicle (Multi-UAV) communication network in environments beyond the fifth generation and sixth generation (B5G / 6G), with a focus on the challenges posed by redundant data. We propose a linear optimization model...

Hyperspectral image (HSI) has more spectral information than conventional images, which helps to distinguish targets in a complex scene more accurately. However, HSI typically has a low spatial resolution, which limits their application scenarios. To achieve high-resolution HSI, we propose a spectra...

Uncertainty analysis of classification or regression models is a key feature of probabilistic approaches to supervised learning, allowing the assessment of how trustworthy predictions are. Just as boosting algorithms aim at obtaining accurate ensembles of simple classifiers, using a process guided b...

Metallic gratings have drawn great attention over the past few years due to effective light trapping and power conversion efficiency enhancement in organic solar cells (OSCs). Novel OSCs incorporated short-pitch metallic grating into the conventional OSCs as the back electrode is presented. The opti...

A gas pressure sensor based on Brillouin scattering in a microscaled fiber is experimentally demonstrated. The microscaled fiber with a diameter of 1.9 &#x03BC;m is drawn from a commercial single-mode fiber. A Brillouin spectrum with multipeak structure is observed due to the coupling between lo...
