Silicon is a poor light-emitter due to its indirect bandgap nature. This paper aims to increase the intensity of the light emission from silicon by implantation of boron which will lead to the formation of dislocation loops between the lattice structures. Prior to that, the silicon samples were implanted with high concentration of carbon. Photoluminescence (PL) measurements were carried out to observe the emission in silicon at near infrared region. The temperatures were varied from 10K to 100K to study the effect of temperature towards the peak luminescence intensity. By observing the PL spectra, there are two main peaks that can be seen at ~1112 nm and 1170 nm. Both peaks show significantly higher intensities in the samples incorporated with boron.","PeriodicalId":6758,"journal":{"name":"2020 IEEE 8th International Conference on Photonics (ICP)","volume":"106 2","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91497499","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}

To date, the conversion efficiency of the GaSb TPV cell remains low due to the presence of electrical and spectral losses. In this study, a GaSb TPV cell model is developed using the Silvaco TCAD simulation software. Validation on the simulation model was performed under atmospheric (AM) 1.5 standard test condition (STC) and TPV illumination conditions. Through the validation processes, a set of GaSb physical parameters that are reliable to be used for GaSb TPV cell simulation was established. Under AM1.5 testing condition, the electrical characteristic and performance of GaSb TPV of the reference cell were obtained from an experimental characterization on commercialized devices. A deviation in fill factor and cell efficiency was found between the cell sample and simulation model under AM1.5 illumination. This is due to the presence of resistance losses in the device. Nevertheless, a percentage error of below 3% was achieved under 1200 ° C TPV spectrum. Besides, it was found that a spectral filter that cuts at 2 μm increases the cell efficiency from 11.51% to 19.10% with a power output of 1.33 W/cm2. The finding in this study demonstrates the importance of minimizing the electrical losses and the determination of an optimal filtered spectrum wavelength for developing highperformance GaSb TPV cell.","PeriodicalId":6758,"journal":{"name":"2020 IEEE 8th International Conference on Photonics (ICP)","volume":"7 1","pages":"44-47"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90205195","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 conventional DCS-BOTDR uses two pulsed probes having slightly different in pulse duration; the duration difference between the pulses enables sub-meter spatial resolution. In the new coded DCS-BOTDR, the narrow pulse was modulated with Golay code via intensity modulation scheme to achieve higher BFS resolution and at the same time attain sub-meter spatial resolution. By using 8 bits of Golay code in the proof-of-concept experiment, we have achieved 40 cm spatial resolution and 3.47 MHz Brillouin frequency accuracy in measuring a 1280 m fiber.","PeriodicalId":6758,"journal":{"name":"2020 IEEE 8th International Conference on Photonics (ICP)","volume":"4 1","pages":"11-12"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81799742","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 main focus of this work was the integration of SMTF into linear cavity fiber laser to simplify the sensing output. The optimum dimension of the tapered optical fiber used was 5mm transition length, waist length of 10mm and waist diameter of $12mu mathrm{m}$, which was able to produce a single lasing wavelength with suppressed side modes. Linear shifts to the laser with R2 value of 0.970 was observed as the sensor was introduced to increment in the NaCl concentration from 0 to $10mu mathrm{M}$. The integrated SMTF yielded a sensitivity of $0.455mathrm{nm}1mu mathrm{M}$.

In the present work, photonic crystal of multilayer structure as $(mathrm{AB})3^{3}mathrm{D})(mathrm{BA})^{3}$ is considered to study the effect of intensity of light on transmission properties. SiN medium is used as higher refractive index as well as the defect layer with different thickness. As a defect layer it produces a defect mode inside photonic band gap region of transmission spectra. SiN material is used as Kerr nonlinear material whose refractive index depends upon intensity of light, therefore this defect mode is shifted due to the changes in refractive index of SiN induced by intensity.
