We propose the use of a commercial coherent transceiver to increase the transmission speed of a short-reach optical communication system over 300 m OM3 fiber. The performance of the system is studied in terms of bit rate as a function of the power budget margin (PBM) defined as the extra attenuation that can be introduced on the optical path. We investigate polarization multiplexed (PM) QPSK and 16-QAM modulation formats achieving up to 400 Gbps net bit rate transmission. Moreover, we analyze the impact of the lateral offset introduced by the connectors between MMF segments, showing decreasing PBM for increasing lateral offset. Nevertheless, PBM in excess of 28 dB for PM-QPSK modulation at 100G and 200G, 23 dB for 200G PM-16QAM modulation and 16 dB for 400G PM-16QAM, shows that commercial coherent transceivers can be used on MMF links up to much higher bit rates than those achieved by current VCSEL+direct detection based systems, provided that connections along the MMF have connectors connectors with offsets in the 3 $mu m$ to 6 $mu m$ range.","PeriodicalId":227957,"journal":{"name":"2022 Italian Conference on Optics and Photonics (ICOP)","volume":"38 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":"130720031","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}

Here, we selected anisotropic gold nanorods for their outstanding multiplexability and intrinsic brightness with respect to usual gold nanospheres. In particular, we compared two prominent strategies of functionalization with oligonucleotides to detect a specific DNA target, i.e. direct thiolation with a mercapto-probe, or amidation with an amino-probe in association with a carboxy-cross-linker. We found that the former provides much more consistent results, at the expense of greater complexity.","PeriodicalId":227957,"journal":{"name":"2022 Italian Conference on Optics and Photonics (ICOP)","volume":"47 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":"124774659","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}

One of the most powerful spectroscopic approach to nanoscale is Tip-Enhanced Raman Spectroscopy (TERS). TERS combines the fingerprint character of Raman spectroscopy with the high spatial resolution of scanning probe microscopies (SPM), by taking advantage of plasmonic nanostructures placed at the apex of a SPM probe. Thanks to the excitation of Localized Surface Plasmon Resonances (LSPR), such system behaves as a nano-antenna, able to explore surfaces with nanometric spatial resolution and sensitivity up to single molecule level. Herein, we report on the fabrication and characterization of newly conceived nano-antennas. In particular, we illustrate a top-down approach for TERS tip fabrication, based on the solid-state dewetting of metal-sputtered Atomic-Force Microscopy probes. Such approach produces AFM-TERS tips, exhibiting high reproducibility and efficiency.","PeriodicalId":227957,"journal":{"name":"2022 Italian Conference on Optics and Photonics (ICOP)","volume":"5 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":"121226917","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}

However, the increasing complexity of the employed neuromorphic models might pose issues in terms of required computing resources and energy to run these tasks. Optical solutions, especially exploiting integrated photonics, are promising to effectively run neuromorphic tasks, exploiting highspeed and low-power elements. In this paper, we propose to exploit cascaded low-loss and low-driving-voltage travelling wave Lithium Niobate on Insulator (LNOI) modulators to perform multiply-accumulate operations at high speed and low power consumption. Thanks to the moderate losses, the same input can be split to multiple weight modulators, which increases the energy efficiency. Simulations of computer vision tasks on well known datasets show that the proposed solution, notwithstanding the limitations due to the analog photonic physical layer, achieves a good accuracy with limited degradation with respect to traditional digital electronic implementations.","PeriodicalId":227957,"journal":{"name":"2022 Italian Conference on Optics and Photonics (ICOP)","volume":"31 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":"127374288","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}
