The thickness of 6 nm SRL of conventional structure (sample A) is divided equally with 2 nm thickness (sample B) by using digital alloy approach. Further, using such approach, this thick 6 nm capping is divided in unequal fashion for sample C (1 nm, 2 nm and 3 nm) and sample D (3 nm, 2 nm and 1 nm) from InAs QD towards top GaAs layer. The In-content inside the SRL of the sample A is 15%, whereas, In-content inside the divided-SRL is considered as 45%, 30% and 15% for all other samples. Such composition of SRLs helps in reducing the In-out diffusion, minimizing the lattice mismatch at InAs QD-SRL and SRL-top GaAs layer interfaces, and also reduces the strain inside the overall heterostructures. Two strains, namely hydrostatic and biaxial are calculated by using Nextnano for all the structures and compared simultaneously. The hydrostatic strain inside the QD of sample D is reduced by 4.74%, 1.07% and 2.269% and the biaxial strain inside the QD of sample D is improved by 1.66%, 0.696% and 1.276% as compared to that of samples A, B and C, respectively. The computed PL emission of samples A, B, C and D are observed to be 1305 nm, 1365 nm, 1349 nm and 1375 nm, respectively. Hence, sample D is the optimum choice for fabricating future opto-electronic devices.","PeriodicalId":13820,"journal":{"name":"International Conference on Nanoscience, Engineering and Technology (ICONSET 2011)","volume":"34 2","pages":"122000E - 122000E-7"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72567026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The innovation of the MS is its operation on the principle of coupled resonances, whereby coupling the classical narrowband Fabry-Perot (FP) resonance and a broadband cavity mode (CM) resonance can tune its dispersive spectral behavior. This results in the MS transmitting a narrow passband within a broad stopband for a focused light cone. Compared to conventional methods, this novel approach has the potential to reduce the size, weight, and power (SWaP) of a HSI system. Currently, hyperspectral sensors require bulky dispersion controlling optics to collimate the incoming beam due to physical limitations set forth by the disperser. Because the disperser is usually a transmission/reflection grating, the angle of the incident beam significantly impacts whether the correct wavelength is incident on the sensor. At even a slightly off-normal (AoI), the beam could either miss the sensor entirely, or create cross talk between adjacent pixels. This fundamental limitation produces difficulties in managing obliquely incident light, hence the need for collimation. To get around this, the AoI insensitive metamaterial will be used in the place of the disperser and collimated optics to properly deliver obliquely incident light to the detector. When applied correctly, the MS can be used within a remote sensing detector to provide high performance spectroscopy that is similar to larger heritage sensors.","PeriodicalId":13820,"journal":{"name":"International Conference on Nanoscience, Engineering and Technology (ICONSET 2011)","volume":"551 1","pages":"121950D - 121950D-6"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90780415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The peak fluorescence emission is located around 345 nm (UV range) and is typically analyzed through spectroscopic measurements. In general, optical fibers show poor transmission in this wavelength range, and this hinders the use of this waveguides for tryptophan fluorescence monitoring or other molecule with UV fluorescence. However, down conversion phosphors attached to conventional fiber tips may provide a mechanism for improved fluorescence detection in this spectral range. In this work, we explore the use of UV-sensitive phosphors hosted by a polymer matrix that can be incorporated on the tip of conventional optical fibers for UV-fluorescence monitoring. In particular, we evaluate the performance of Eu-activated phosphors absorbing at 345 nm and emitting multiple fluorescence peaks in the 450-650 nm range. The phosphors are incorporated in polydimethylsiloxane (PDMS) by a simple mixing procedure, yielding a UV-sensitive polymer composite. Membranes of this composited were fabricated using different concentrations of the phosphors (i.e. 0.1, 0.5, 2.5, 12.5 and 62.5% wt./wt.), and their optical and thermal properties were evaluated. The polymer composites show good thermal stability and can be incorporated on conventional optical fibers. The resulting fiber optic fluorosensors may serve as a tool for fluorescence monitoring of tryptophan or other UV emitters.","PeriodicalId":13820,"journal":{"name":"International Conference on Nanoscience, Engineering and Technology (ICONSET 2011)","volume":"4 1","pages":"122020B - 122020B-9"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89002187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
