FELs can exploit, in a time-resolved approach, spectroscopies daily employed at synchrotron light sources, mostly combining EUV, SXR and HXR pulses with optical ones. Nonetheless, the next advances in ultrafast x-Ray science are strongly linked to the extension of these time-resolved schemes to perform experiments engaging exclusively EUV, SXR and HXR pulses, so triggering (and probing) matter at its (or nearby) electronic resonance(s), to reveal the microscopic mechanisms hiding behind matter phases of primary interest for broadband applications. Indeed, designing the next generation of quantum devices, as well as tailoring a new classes of biomolecules for pharmacological applications, are just two examples that can be strongly boosted by means of this optical approach. To do this, is mandatory to split and delay (in time) FELs pulses, without impacting on both the radiation coherence properties and on the photon transport. At the seeded FERMI FEL (Trieste, Italy) this goal is committed by the optical device known as AC/DC, which stands for the Auto Correlator/Delay Creator, designed to split the incoming EUV and/or SXR pulse, introducing a tunable delay between these two pulses, marked by an intrinsic resolution in the sub-fs, and aided by an opto-numerical pointing feedback system.","PeriodicalId":376481,"journal":{"name":"Optics + Optoelectronics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133129052","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}

Nanotechnology involving piezoelectric materials is a key research direction, with benefits expected from nanostructuring and the replacement of toxic materials. Piezoelectric nanocomposites based on semiconducting nanowires (NWs) are an alternative to thin films with nanostructuration benefits, such as low temperature fabrication and higher flexibility than thin films. In addition, they exhibit larger piezoelectric coefficient than their thin films counterparts. In this work we study the piezoelectric performance of vertically grown ZnO NWs based on Finite Element simulations in the PFM (Piezoresponse Force Microscopy) configuration. In this AFM (Atomic Force Microscope) mode, the AFM tip is placed in contact with the top surface of the NW while applying a voltage, thus inducing a deformation of the structure by the reverse piezoelectric effect. Different parameters are assessed: the effect of the surrounding air, the NW size and geometry and the effect of the semiconducting properties, in particular the doping level and surface traps density. The results are compared to previous theoretical approaches and experimental findings.","PeriodicalId":376481,"journal":{"name":"Optics + Optoelectronics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114900644","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}

When preparing experiments for accelerating electron with lasers, people are considering focal lengths that can range from a few meters up to tens of meters. Telescopic zoom systems made of three spherical mirrors can be designed for such purpose. After a first attempt to design such system based on simple “a priori” parameters, a general algebraic theory has been investigated and shows that there are always solutions with no spherical aberration. When all mirrors are placed off-axis to avoid obscuration of the beam, it is possible to show that there are still solutions that minimize aberrations. When changing the distance between the mirrors, we can obtain a focal excursion of the system while the final focal spot is fixed. Of course, the goal of the study is to find what are the solutions that minimize aberrations for a given numerical aperture over a given zoom range. I have built and tested three zoom systems based on different solutions and I have been able to show that there are simple alignment procedures for generating a fixed focal spot over the zoom range. In this paper, a step-by-step analysis including damage fluence considerations for designing the 3-mirror zoom system will be detailed.","PeriodicalId":376481,"journal":{"name":"Optics + Optoelectronics","volume":"128 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120874209","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}

Indeed, such films can be assimilated as transducers thanks to their ability to convert light into displacement with strokes up to several millimeters. By adjusting the incident light parameters (wavelength, exposure time…) the photomobile films actuation can be controlled to answer many applications requesting high displacements and low forces. In these regards, the behaviour of the photomobile films were characterized prior to their integration in more complex devices. Then, several proof-of-concepts of these devices were manufactured to try to bring new functionalities to the market such as light driven optical switch, optical micro-valve, and deflector: The optical switch features interesting properties in term of electrical insulation by eliminating the dark currents responsible for noise in image sensors. It also exploits the large stroke of the photomobile films to achieve the standard electrical insulation distance versus emitter voltage. Light driven micro-valves/micro-pumps are suitable for delivering a small quantity of fluids with high precision for example in medical devices. Using this technology, a fluid circuit can be opened and closed when light is switched from on to off (or inversely) without embedded electric power. Optical deflectors are used widely in optical pointing applications where fast responses and/or high precisions are critical. An appropriate understanding of the photomobile films behaviour enables to control the direction of the beam deflection within large angular ranges.","PeriodicalId":376481,"journal":{"name":"Optics + Optoelectronics","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126163692","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}
