Combining the advantages of both top-down and bottom-up fabrication processes, this approach offers an exceptional flexibility for achieving semiconductor micro- and nanotube structures with an epitaxially smooth surface and well controlled diameters and wall thicknesses using a single photolithography step. However, lasing in such tube structures has hitherto not been demonstrated. In this context, we have performed a detailed investigation of the fabrication and characterization of rolled-up micro- and nanotubes, with the incorporation of self-organized InGaAs/GaAs quantum dots as the gain media. We have achieved, for the first time, lasing in rolled-up semiconductor tubes at room temperature. The devices are characterized an ultralow threshold power (~ 4 μW), an intrinsic lasing linewidth of ~ 0.2–0.3 nm, and a linear polarization with the electric field parallel to the tube surface.","PeriodicalId":367324,"journal":{"name":"2010 IEEE Photonics Society Winter Topicals Meeting Series (WTM)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123715212","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}

Performance is assessed using selected samples of organic, pharmaceutical and energetic compounds with absorption peak positions in the 0.1–3.5 THz range, with results >99% confidence without the use of HDPE sample references using standard correlation and partial-least-squares (PLS) techniques. The current state of THz Air Photonics, where selected gases are used as both THz emitter and detector, and how it relates to real-time identification will also be presented.","PeriodicalId":367324,"journal":{"name":"2010 IEEE Photonics Society Winter Topicals Meeting Series (WTM)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133579106","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}
