In this case a narrow beam evolves as a hollow double-walled cylinder of light behind the exit facet of a crystal. Despite of almost two-centuries-long research, CR was slow with practical applications, mainly due to the difficulties associated with cutting of the biaxial crystals with the necessary precision. However, a number of recent papers report on the emerging applications of CR for the realisation of ultra-efficient CR lasers, lasers with CR output, optical trapping with CR beams, utilisation of CR for quantum-computing, cryptography and super-resolution microscopy (see e.g. [1] and references therein). However, one of the most novel and intriguing phenomena within the CR are associated with utilization of vortex input beams. These are capable to completely change the familiar CR patterns [2] and trigger many new applications. In this sense, studies of CR with Laguerre-Gaussian beams LGl0, which are the simplest vortices, may be very fruitful (here, I is the index determining vortex charge): These already have demonstrated specific new properties of CR, such as formation of a multi-ring image in the Lloyd plane [2].","PeriodicalId":6714,"journal":{"name":"2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)","volume":"1 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2019-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75501093","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}

Previous Ge on SI SPAD devices using mesa structures have shown high dark count rate (DCR) and low single photon detection efficiency (SPDE) [2]. The novel planar device design demonstrated here shows low DCR and high SPDE at short-wave infrared wavelengths. The novel design allows better performance by confining the high field regions using an implanted charge sheet and small top contact region. This design removes the interaction between etched sidewalls and high electric fields seen in mesa devices. We have fabricated devices with a 100 μm diameter charge sheet and a 90 μ m diameter top contact. TCSPC measurements were taken at 78 K, 100 K, 125 K, using 1310 nm light with << 1 photon per pulse on average and 50 ns gate times (Fig. 1). A record high SPDE of 38% for Ge-on-Si SPADs was measured for a device temperature of 125 K with an excess bias of 5.5 %, and a record low NEP of 2× 10−16WHz−1/2 was demonstrated at 78 K.","PeriodicalId":6714,"journal":{"name":"2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)","volume":"109 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2019-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80697209","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}

Material characterization using such ultrafast laser-induced ultrasound pulses provides access to a frequency range that is inaccessible by any other means. Our objective is to study the optical and acoustic properties of materials by generating and detecting ultrasound waves with ultrafast laser pulses. To generate high frequency acoustic waves in a way that also optimizes their detection, we use a pair of crossed 40 fs femtosecond pump pulses at 400 nm wavelength to project interference fringes on the surface of thin metal films. Because ultrasound is only generated in the interference maxima, this approach produces a spatially periodic array of acoustic pulses. The acoustic pulses propagate through the film and are reflected at the back surface. A delayed probe pulse (30 fs, 800 nm) then detects the returning acoustic echo by detecting a change in the optical response that occurs every time an acoustic echo returns to the surface. Because a periodic array of ultrasound waves was produced, we can detect the first order diffraction of the probe beam by this ‘acoustic grating’. By performing these measurements in thin free-standing metal membranes, the influence of substrate interfaces is eliminated, and acoustic attenuation is only caused by propagation in the metal, providing clean measurements of the metal parameters without external factors.","PeriodicalId":6714,"journal":{"name":"2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)","volume":"9 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2019-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78311570","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}
