Colloidal quantum dots (CQDs) have emerged as a versatile platform for optoelectronic device fabrication, offering affordability, low-temperature synthesis, and scalability. Specifically, mercury chalcogenide CQDs exhibit notable intraband absorption in the mid-IR region. In this study, we explore an intraband HgSe-HgTe CQD photodetector structure tailored for mid-IR light detection. Through numerical optimization, we engineer detectivity by varying key design parameters—the film doping density, CQD diameter, and number of periods in the active layer—under different temperatures and biases. Results indicate that, at 60 K and 1 V bias, our optimally designed HgSe-HgTe CQD IR photodetector attains a peak detectivity of 8.14×1010 Jones for a film doping density of 1019 cm−3 of HgSe CQDs, 9.34×1010 Jones for HgSe CQDs with a 4.8 nm diameter, and 8.72×1010 Jones for 9 periods of HgSe-HgTe CQDs.","PeriodicalId":16449,"journal":{"name":"Journal of Nanophotonics","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139657383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the optical properties of GST material having thicknesses of 130 to 230 nm on two commonly used substrates, i.e., silicon (Si) and silicon dioxide (SiO2), are investigated in detail. The phase-change property of GST plays an important role in tuning the resonant wavelength, absorption, and transmission loss in the ring resonator as its crystalline state has a higher refractive index (RI) compared with the amorphous state. Due to the phase-change property of the GST material, the effective RI of the waveguide core changes. A patch of GST is embedded on a ring resonator to optimize the response of light coupled in the ring and straight waveguide, that is tunable between its amorphous phase (a-GST) and crystalline (c-GST) phase. The difference in refractive indices between the two states of a phase-change material (PCM) renders it an optimal choice for the optical active devices used in light modulation and switching applications. The GST is employed as an active material in the proposed structure as it is significantly stable and results in reduced insertion loss (IL) compared with other PCMs. In the proposed design of the ring resonator, the finite-difference time-domain simulation demonstrates high extinction ratios of 16.05 and 20.50 dB at the THROUGH and DROP ports, respectively. Moreover, the low insertion losses (IL) of 0.33 dB at the THROUGH port in crystalline phase and 0.8 dB at the DROP port in amorphous phase, have been observed. The Q-factor of the ring resonator without a GST patch is 5.18×105, whereas with a GST patch, it is 5.13×105 and 1.28×105 in the amorphous and crystalline phases, respectively.","PeriodicalId":16449,"journal":{"name":"Journal of Nanophotonics","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140007764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the PICs, photonic devices with compatible materials, compact footprint, high-performance, and sophisticated functionalities are necessary building blocks. Design optimization to implement such devices for target applications and requirements are of critical importance. In this respect, inverse design methods, including iterative optimizations and deep neural networks, have demonstrated significant advantages over the traditional simulation-based trial-and-error optimization approach. We provide an overview of the recent progress on the inverse designs for the integrated photonic devices. The principles and procedure of the inverse design methods are presented and discussed, followed by a summary of the methods employed for specific integrated photonic devices in different integrated photonics material platforms. Finally, topics of future applications and fabrication constraints for the inverse design methods are discussed.","PeriodicalId":16449,"journal":{"name":"Journal of Nanophotonics","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139584435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel all-optical first to third order linear ODEs solutions with tunable constant coefficients using double Sagnac rings coupled Mach–Zehnder-interferometer (DSMZI) on silicon waveguide chips are proposed. The structural composition and size of the DSMZI have been designed, and the working principles of its first to third order ODEs solutions have been derived. By varying the input electric heating power of the thermal-optical phase shifters of the individual arms of the MZI, the constant-coefficient of the differential equation can be simply tuned in large scope. It is demonstrated that the constant coefficient k ranges from 0.0015/ps to 0.092/ps for the first-order ODE. The constant coefficient p of the second-order ODE solver can be continuously tuned from 0.013/ps to 0.174/ps, correspondingly with the q varying from 0.00004225/ps2 to 0.007569/ps2. Three constant coefficients u, v, and w of the third-order ODE can be continuously tuned from 0.105/ps to 0.252/ps, 0.003675/ps2 to 0.021168/ps2, and 0.00004288/ps3 to 0.0005927/ps3, respectively. The all-optical ODE solvers with the DSMZI can be easily integrated with other optical components based on silicon on insulator, which can provide a path for future artificial intelligence or big data processing systems in optical computing on silicon waveguide chips.","PeriodicalId":16449,"journal":{"name":"Journal of Nanophotonics","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139055038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
