Here, combined with the surface electronic properties of two-dimensional materials, we analyzed the physical mechanism of the photoelectric effect of a photodetector based on two-dimensional materials. By simulating the light waves of different wavelengths induced on the surface of the photodetector, the changes of its conductivity and absorption rate were analyzed. Since the channel material has an electrically tunable Fermi level, the surface electric field will also be regulated with the Fermi level. Finally, we verified its photoelectric performance by preparing a trilayer graphene device. The results show that the light response of the trilayer graphene photodetector reaches the maximum at 1550 nm, and the surface photoelectric electric field distribution is affected by the Fermi level regulation. Our results show that the performance of graphene photodetectors can be efficiently regulated by Fermi level, which provides theoretical support for the performance improvement and material upgrading of photodetectors in the future.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-5"},"PeriodicalIF":2.1,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10979879","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143937955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The detection of shortwave infrared light lays in the centre of SWIR applications. Conventional SWIR detectors rely on epitaxial semiconductors, which are costly and limited by low manufacturing throughput. Colloidal quantum dots (CQDs) have been developed to unravel these issues and comparable device performances have been achieved after decades’ efforts. While CQDs can offer low-cost alternatives once high-volume maturity level is reached, their widespread adoption in consumer electronics market has been hindered also by concerns on the use of lead/mercury-based materials. Recent advances in heavy-metal-free CQDs, such as silver chalcogenides (Ag2Te) and III-V semiconductors (InAs, InSb), have demonstrated performance metrics, which, in some cases, rival heavy-metal based counterparts. Progress in synthesis, surface passivation, and device engineering have enabled high detectivity (>10¹² Jones), broad spectral tunability (1000–2000 nm), monolithic integration with silicon readout circuits and proof of concept demonstration in image sensor and LIDAR use cases.

However, their output images often exhibit striped noise due to the nonuniform response of the detection system, which significantly affects image quality and visual fidelity. To address challenges such as incomplete stripe removal, potential loss of image details and textures, and the generation of artificial artifacts during destriping, we propose a novel stripe removal method based on a knowledge-embedded diffusion model (KEDM). This approach effectively integrates the spatial distribution characteristics of stripe noise with an innovative, data-driven diffusion network model, creating a hybrid knowledge and data-driven framework for stripe correction. The core components of KEDM are the latent diffusion model (LDM) architecture and the directional wavelet convolution module (DWCM). Specifically, LDM leverages a pretrained variational autoencoder (VAE) to transform the input image into latent feature space for efficient diffusion propagation, reducing computational complexity while preserving image restoration quality. Meanwhile, DWCM uses wavelet convolution operations to construct prior loss functions for stripe noise, precisely guiding the diffusion reconstruction process to achieve a clean, stripe-free image. Empirical evaluations on several benchmark datasets demonstrate that the proposed KEDM outperforms other state-of-the-art destriping algorithms in terms of visual quality and quantitative metrics, validating its excellent performance.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-9"},"PeriodicalIF":2.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10978030","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigate a three-node quantum communication system, where Alice, the transmitter, sends quantum-encoded binary information to Bob, the ultimate receiver, via an intermediate relay node, Charlie. By introducing Charlie, the end-to-end transmission is divided into two shorter FSO links, improving signal stability and reliability in the presence of severe atmospheric turbulence and noise. This work proposes a quantum relaying method specifically designed for FSO links and examines the impact of two-hop relaying in terms of the probability of error. The Helstrom error bound is derived to assess the system's detection limits, while density operator calculations are performed to characterize the quantum relaying setup. In addition, a closed-form expression is obtained for key system performance metrics. The findings offer valuable insights into optimizing quantum relaying strategies for long-distance quantum communication over FSO channels.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-15"},"PeriodicalIF":2.1,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10972305","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By utilizing an electro-optic comb generator that can adjust the repetition rate and central wavelength, this system generates numerous wavelengths from a single laser, serving as individual laser sources for spectral beam combining. Additionally, the system can incorporate a single line-broadener for all channels together for suppressing stimulated Brillouin scattering (SBS). A de-multiplexer is used to separate distinct wavelengths into individual fiber ports. By employing external phase modulation with white noise, the system can adjust the linewidth from a single frequency to 4 GHz. Furthermore, superior SBS control is achieved by tailoring the lineshape in the de-multiplexer, which reduces feedback-assisted SBS. With the customized lineshape, the SBS threshold of the system increases by <inline-formula><tex-math>$>$</tex-math></inline-formula>50%.

To study the impact of turbulence intensity on secret key extraction rate in atmospheric optical channels, this paper conducted a bi-directional synchronous atmospheric channel laser transmission experiment, analyzed the experimental data from three different time periods, and tested the Kolmogorov-Smirnov (KS) fitting efficiency values for five types of probability distribution normalized received signals. Comparative analysis shows that Johnson SB and Log-Normal distributions have the most ideal fitting effects on data. Based on these distribution parameters, a theoretical model of key capacity was constructed. The Monte Carlo method was used to simulate the secret key extraction rates under different turbulence intensities and different probability distribution models. The analysis results show that under weak turbulence conditions, using Johnson SB distribution yields about 87% higher average maximum secret key extraction rate than using Log-Normal distribution; under medium turbulence conditions, there is no significant difference in secret key extraction rates between the two distribution models. Compared with Log-Normal distribution, Johnson SB distribution is more suitable for secret key extraction under medium to weak turbulence intensities.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-9"},"PeriodicalIF":2.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10971212","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
