This great temperature value is caused by the strong confinement of electric field that is due to the covering gold nano heaters with a layer of polymer + dye. A chopper-modulated impinging wave adds a new control mechanism of the thermal response. In this configuration, the proposed device reveals a maximum temperature variation of $60^{circ} mathrm{C}$ in a period (1Hz frequency). This photo-thermal behaviour can be useful for the development of breakthrough devices in emerging fields of precision medicine and nano reactor where the control of local heating is of paramount importance.","PeriodicalId":227957,"journal":{"name":"2022 Italian Conference on Optics and Photonics (ICOP)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131883538","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}

Health and cancer risk arising from these compounds makes it quite urgent to monitor them in air, soil, and water. Since their concentrations in the environment are usually low (order of ng/L in water), highly sensitive techniques are required. Thanks to the large amount of structural information that it can offer, Surface Enhanced Raman Spectroscopy (SERS) has proven to be an effective alternative to traditional chromatographic techniques for the detection of PAHs. By exploiting the plasmonic properties of metallic nanostructures, this technique allows the detection of very low analyte concentration (nano-and pico-molar range), achieving even the limit of single-molecule detection. However, due to the ineffective adsorption of PAHs onto metallic SERS-active substrates, these surfaces are generally functionalized to increase their adhesion. Such chemical modifications can surely improve the selectivity of selected compounds but might hinder the effective direct contact of analytes to the substrate surface contributing to the background SERS signal. Herein, we propose a simple and effective nanofabrication procedure to produce large-scale 3D nanoporous Ag-based SERS substrates which exhibit excellent spatial reproducibility and EF of about 107. Our substrates can detect polycyclic aromatic hydrocarbons dispersed in water without any functionalization of the surface, reaching a limit of detection (LOD) of ~20 nM for pyrene (PYR). As matter of fact, the nanoporous nature combines a high density of hotspots with the capacity to trap PAH molecules through not covalent bonding, facilitating their adhesion to the metallic surface. In perspective, our outcomes demonstrate the high potentiality of our approach for chemical sensing and environmental control applications.","PeriodicalId":227957,"journal":{"name":"2022 Italian Conference on Optics and Photonics (ICOP)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124565972","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}

We analyze different optimization methods for PAM-2 (NRZ) and PAM-4 modulation formats, based on grid search methods and analytical closed-form solutions for decision thresholds and PAM-4 internal levels. We develop our study on a simulated optical IM-DD system, transmitting at a Baud Rate Rs=50 GBaud (i.e., 50 Gbps for NRZ, 100 Gbps for PAM-4). We assess power budget gain in terms of Optical Path Loss (OPL) with respect to nominal thresholds and levels, determining that optimizations are effective (i.e., approximately 1 dB OPL gain) when the system has moderate bandwidth limitations ($B_{3dB} gt 0.5 cdot R_{s}$).

The improved resolution opens new opportunities in the fabrication of next-generation nanoscale devices such as metalenses, photonic circuits to name a few and in thermoplamonics.
