In this paper, an experimental link for underwater vortex optical communication is constructed, and the underwater transmission and communication characteristics of Gaussian beams and BG vortex beams with different orders are investigated under the seawater channel conditions of air bubbles, sediment, and turbulence. The light intensity images, beam drift, and scintillation indices are analyzed, the bit error rate (BER) during communication is calculated, and the self-healing characteristics of the BG vortex beams in underwater channel environments with obstacles are investigated. The results show that the BG vortex beam has lower beam drift, optical intensity scintillation, and more stable underwater data transmission performance compared with the Gaussian beam under various simulated ocean channel conditions, and the higher-order BG beam has better transmission performance than the zero-order BG beam. This research provides a robust and useful alternative to withstand ocean turbulence and improve the reliability and capacity of optical communication systems.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 5","pages":"1-8"},"PeriodicalIF":2.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within the framework of the proposed simulation model, the relationship between the efficiency of laser mode light output through the surface and the geometric characteristics of the photonic crystal has been studied. As an example, we performed calculations and analysis of optical output losses in a waveguide heterostructure based on the AlGaAs/InGaAs material system. The study focused on square symmetry photonic crystals with simple geometric shapes, including circles and triangles. The results demonstrate that surface-emitting lasers designed in planar structures using photonic crystals based on circular holes have low radiation output efficiency. Efficient light output can be achieved by using triangular hole shapes with a fill factor greater than 0.1-0.2, while the symmetry of the triangular hole significantly influences the output efficiency. The fill factor also determines the mode discrimination and the conditions for single-mode or multi-mode operation.

In particular, mean lock-time, the lock-time averaged over a random initial phase difference between the two laser signals, is systematically investigated. The study, aided by asymptotic stability and phase-space trajectory analyses, shows that the dynamics of OIL lasers is quite complex as well as diverse in its behavior. Findings involving the mean lock-time indicate that it is fairly insensitive to frequency detuning except near the locking edge, wherein extremely large variations can occur, ranging from a very small to a very large value in a narrow interval. It is also found that there is a trend reversal of the mean lock-time with respect to the injection strength; after initially undergoing a decrease with increasing injection level, the lock-time starts to increase once again beyond a certain injection strength. There are also some interesting features predicted, such as instantaneous locking and pseudo-stable behavior. The transient process following switching off of the injected light is also briefly investigated and compared to the injection-locking process. The results of this research should provide useful insight when exploring the feasibility, limitations, and design guidelines of various potential OIL applications in which the response speed is of importance.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 3","pages":"1-16"},"PeriodicalIF":2.2,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Incorporating a thin AZO layer into the HPW enables vertical and lateral plasmonic mode confinement. By inducing carrier changes electrically in AZO, we achieve the epsilon-near-zero (ENZ) state, facilitating efficient intensity and phase modulation across a wavelength range of 1500 nm to 1650nm. Optimized device geometry ensures proficient electro-optic coupling between the dielectric waveguide mode and the surface plasmon mode, resulting in lower losses compared to conventional HPWs. The extinction ratio (ER) ranges from 13 dB/<inline-formula> <tex-math>$mu $ </tex-math></inline-formula>m to 45 dB/<inline-formula> <tex-math>$mu $ </tex-math></inline-formula>m at a low voltage of 1 V, with modulation efficiency spanning from 2.75 V-<inline-formula> <tex-math>$mu $ </tex-math></inline-formula>m to 2.90 V-<inline-formula> <tex-math>$mu $ </tex-math></inline-formula>m for wavelengths between 1500 nm and 1650 nm. We conduct a comparative analysis with another popular ENZ material, Indium Tin Oxide (ITO), demonstrating that the AZO-based modulator, with its high carrier mobility, outperforms the ITO-based modulator. AZO, as an ENZ material, holds transformative potential for optical modulation due to its unique electro-optical properties and compatibility with HPWs, offering significant advantages for high-speed, efficient, and compact optical modulators. Our proposed modulation scheme is poised to play a crucial role in advancing optical communication, quantum computing, and quantum sensing technologies.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 3","pages":"1-8"},"PeriodicalIF":2.2,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144481885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
