The majority of fiber lasers produce ultrashort pulses thanks to nonlinear optical elements called saturable absorbers (SA).

Recently, at 1.5 µm, we report the highest pulse energy extracted from a fiber oscillator passively mode-locked by MQW-SA [1]. The discovery of the nonlinear optical behaviour of carbon nanotubes (CNT-SA) makes them attractive materials for replacing MQW-SA [2].","PeriodicalId":6331,"journal":{"name":"2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC)","volume":"30 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2011-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72903826","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}

It featured high compactness, robustness, configurability and excellent confinement of light and was able to demonstrate its ability to sense currents with a 1 µs rise time.

However, this is usually not practical in terms of a balance between computation time and accuracy.

Based on a series of experimental studies for hard thin films such diamond-like carbon and TiN [2,3], we have shown that near-field enhanced with femtosecond (fs) laser pulses plays the essential role in initiating the nanoscale ablation on the target surface [4], and the origin of nano-periodicity observed can be attributed to the excitation of surface plasmon polaritons (SPPs) in the surface layer [5] where the dielectric properties are rapidly changed due to the generation of high-density free electrons.","PeriodicalId":6331,"journal":{"name":"2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC)","volume":"27 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2011-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75470970","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}

In particular, clock generation has been demonstrated by using a programmable notch filter at the output of a 40 GHz QDash-ML laser [5]. Selection from two to three longitudinal modes at a given wavelength separation allows for the generation of sinusoidal clock signals at different repetition rates. In this work, an alternative approach based on optical time-domain multiplexing is experimentally investigated. Optical pulse-streams at 80, 160 and 320 GHz featuring optical signal-to-noise-ratios of 12, 9 and 6 dB, respectively, are obtained. Time-domain multiplexed pulses exhibit a full-width at half maximum (FWHM) of 1.8 ps irrespective of the pulse repetition rate.","PeriodicalId":6331,"journal":{"name":"2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC)","volume":"32 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2011-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73859465","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}

Good physical insight was obtained for THz QCLs employing a single plasmon waveguide (surface plasmon waveguide) [2,3]. In comparison to that the double plasmon or metal-metal waveguide QCL uses a metal/semiconductor/metal structure as a waveguide. THz QCLs with this type of waveguide are showing the highest operating temperatures so far [4]. The metal-metal THz QCLs confine the whole mode in the active region of subwavelength size. In order to investigate metal-metal THz QCLs by THz pulses an efficient method of THz pulse launching needs to be employed. Several methods for coupling of free space THz pulses into the subwavelength waveguide, such as horn antenna, gratings or lenses can be used. A further method is a waveguide emitter [5,6] which benefits from the near infrared excitation beam focus which is much smaller than the corresponding THz focus.","PeriodicalId":6331,"journal":{"name":"2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC)","volume":"17 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2011-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72744431","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}
