However, through k-domain method and simulation analysis, this letter finds that although SG perform well in 2D simulation, their effect drops sharply in 3D space, a phenomenon being overlooked in the community. This letter explains the diffraction mechanism of LEDs with nanostructure in 2D and 3D space through K-domain analysis, and reveals the inaccuracy of simulating LED with SG in 2D space. Unlike SG, PhCA offers diffraction in two directions and may be more suitable for LEDs.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"60 3","pages":"1-6"},"PeriodicalIF":2.5,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140577945","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}

Despite maturity at the production level, the underlying causes of noise and dark current need clarification for further improvement. We studied the dark current and noise characteristics in PIN In0.53Ga0.47As photodiodes with different mesa sizes. The dark current noise exhibits a clear spectral 1/\u0000<inline-formula> <tex-math>$f$ </tex-math></inline-formula>\u0000 shape in all conditions. The results at low temperatures suggest that the dark current is dominated by the sidewall shunt paths while generation-recombination dark current comes into play at high temperatures. The noise intensity follows the squared leakage current in the temperature range of 100-240 K. Since the extracted activation energy of 1/\u0000<inline-formula> <tex-math>$f$ </tex-math></inline-formula>\u0000 noise approximates that of the surface leakage current, suggesting that the surface leakage current may be the primary factor of the 1/\u0000<inline-formula> <tex-math>$f$ </tex-math></inline-formula>\u0000 noise.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"60 3","pages":"1-5"},"PeriodicalIF":2.5,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140577794","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}

The proposed scheme can act as a fully analogue system for nonlinear signal processing directly in the optical domain. By exploiting the rich Kerr-induced nonlinearities, multiple nonlinear transformations of an input signal can be generated and used for solving complex nonlinear tasks. We first evaluate the performance of our scheme in the Santa-Fe chaotic time-series prediction. The true power of this processor is revealed in the all-optical nonlinearity compensation in an optical communication scenario where we provide results superior to those offered by strong machine learning algorithms with reduced power consumption and computational complexity. Finally, we showcase how the FWM module can be used as a reconfigurable nonlinear activation module being capable of reproducing characteristic functions such as sigmoid or rectified linear unit.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"60 4","pages":"1-6"},"PeriodicalIF":2.2,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141165599","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}
