The effect of spontaneous emission is modeled by a classical Langevin force entering the equation for the slowly varying waves. The solution of the coupled-wave equations, describing the propagation of four basic waves within the plane of the photonic crystal, is expanded in terms of the solutions of the associated spectral problem, i.e. the laser modes. Expressions are given for photon number, rate of spontaneous emission into the laser mode, Petermann factor and effective Henry factor entering the general formula for the linewidth. The theoretical framework is applied to the calculation of the linewidth-power product of air-hole and all-semiconductor PCSELs. For output powers in the Watt range, intrinsic linewidths in the kHz range are obtained in agreement with recent experimental results.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 1","pages":"1-14"},"PeriodicalIF":2.2,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142993099","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}

This paper presents an automated intelligent design system for semiconductor photodetectors, which is capable of identifying the optimal performance of the photodetector under arbitrary material distribution. The aforementioned method was employed for the design of a modified uni-traveling carrier photodetector (MUTC-PD), exhibiting a bandwidth of 232GHz(@-5V) and an RF output power of 16.799dBm(@100GHz). In comparison to the original structure and traditional manual scanning methods, the bandwidth of this device has been increased by 96GHz and 25GHz, respectively, which serves to illustrate the effectiveness and superiority of this approach. Furthermore, the system is also instrumental in the discovery of new material combinations and structural designs, thereby driving innovation and advancement in the field of semiconductor photodetector technology.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 1","pages":"1-8"},"PeriodicalIF":2.2,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142993098","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}

Double asymmetric barrier layers (DABLs) flanking the active region should efficiently suppress this parasitic recombination. One of the challenges still remaining in DABL lasers is the presence of excited states in the active region. In this work, the impact of such states in quantum dots (QDs) on static and dynamic characteristics of DABL QD lasers is examined. The most dramatic case is considered where carriers can only be captured into the QD excited state before decaying to the ground state and thus contributing to lasing. We show that there exist optimum values for the DC component of the injection current, QD surface density, and cavity length that maximize the laser modulation bandwidth. The maximum bandwidth itself is strongly controlled by intradot relaxation of carriers—while it remains almost unchanged at the excited-to-ground state relaxation times shorter than 0.01 ps, it drops considerably for longer relaxation times in the considered structures. A strict control of the parameters is thus essential in DABL QD lasers to increase their modulation bandwidth.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 1","pages":"1-9"},"PeriodicalIF":2.2,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858660","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 impacts of geometrical parameters and doping concentration are explored for the corresponding dispersion characteristics. By systematically adjusting diverse fiber parameters, it becomes evident that alterations in the curve slope discrepancies between the effective index of the central core and the outer ring directly influence both the optical dispersion peak and bandwidth. Consequently, the optical dispersion characteristics of the designed fiber can be customized to meet specific requirements by adjusting both fiber geometry and doping concentration of germanium dioxide. Further refinement of the fiber’s geometric parameters results in achieving a negative chromatic dispersion value of -203,898 ps/(nm\u0000<inline-formula> <tex-math>$cdot $ </tex-math></inline-formula>\u0000 km) at 1547.9 nm.
