TL;DR: This review analyzes and discusses a variety of advanced full- Colour micro-LED display techniques with a focus on three aspects: growth technique, transfer printing technique and colour conversion technique, aiming to guide the development of full-colour micro- LED display.

TL;DR: An overview of the recent developments in UWOC systems, covering aspects about the system transmitters and receivers, advanced modulation formats and underwater channels and some key technologies to improve transmission capacity are classified and summarized to provide guidance for system design.

TL;DR: In this article, the authors present the generation of femtosecond pulses in ultrafast mode-locked fiber laser using active, passive, hybrid mode-locking techniques, and the emphasis is given to passively modelocked fiber lasers, which plays an indispensable role in medical imaging, space ranging, ophthalmology, terahertz spectroscopy, material micromachining and so on.

TL;DR: In this article, the authors derived the Schawlow-Townes linewidth of a Fabry-Perot resonator for a single-level laser with a single photon coupled to a single lasing mode, based on the principle that the gain elongates the photon-decay time and narrows the Linewidth.

TL;DR: It is proposed that solar cells with the dual functions of energy harvesting and signal acquisition are critical for alleviating energy-related issues and enabling optical wireless communication (OWC) across the satellite–air–ground–ocean (SAGO) boundaries.

TL;DR: This review paper presents an overview of the monolithic and heterogeneous integration of GaN devices and components and various methods for the integration of electronic, optoelectronic, and optical components based on GaN are discussed.

TL;DR: In this article, the authors study the fundamentals of GST-tuned photonics and systematically summarise the progress in this area, and investigate the strategy of designing reversibly switchable GST-based photonic devices and their advantages.

TL;DR: In this paper, an overview of the erbium-doped active media (e.g., Er:YAG, YAG-YAP, Er:GGG, EAG-SrF2, LYF, LYLF, Y2O3, YAP-O3 and KOW, etc.) for laser radiation generation in the spectral range 2.7-3μm is presented.

TL;DR: This paper aims to consolidate the literature, explains the key implementations and reviews the recent developments of microwave photonics instantaneous frequency measurements, and predicts the future research directions and developments.

TL;DR: In this paper, the authors review the field of terahertz (THz) sources which make use of the nonlinear, stimulated polariton scattering (SPS) process.

TL;DR: In this paper, the first watt-level ultrafast laser inscribed Thulium waveguide (WG) laser is reported, with a record-high slope efficiency of 82.7% (with respect to the absorbed pump power), a threshold of only 17mW and a spatially singlemode output with linear polarization.

TL;DR: The progresses of this technology is reviewed, going back from the first historical RF energy harvesting systems and covering the most innovative trends to this date, to improve the understanding of the key points of rectifying antennas’ design for the infrared and visible light and the challenges of device fabrication.

TL;DR: In this article, King Abdullah University of Science and Technology (KAUST) baseline funding baseline funding was discussed and the authors proposed a methodology to evaluate the performance of KAUST.
