An outline analysis is given of the key theoretical issues, such as oscillation and starting conditions, and how the output power scales with frequency. Two techniques for the realisation of the cavity assembly are outlined. The preferred method results in a free-standing gold re-entrant cavity of high surface quality. Field emitter tips are planned for use in this device: the present status of performance of these is described.","PeriodicalId":143116,"journal":{"name":"Proceedings, IEEE Tenth International Conference on Terahertz Electronics","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127009651","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}

Collimated THz beams are observed from surface-field THz emitters and three methods of improving the efficiency of these emitters are demonstrated: (i) by applying a magnetic field, (ii) by reducing the effective refractive index of the device and (iii) by altering the geometry of the device. An enhancement of 21/spl times/ is seen in a prism based GaAs/InAs THz emitter.","PeriodicalId":143116,"journal":{"name":"Proceedings, IEEE Tenth International Conference on Terahertz Electronics","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114753244","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}

Without readjusting the mirrors, smooth tuning of the terahertz-wave over the 0.6/spl sim/2.6 THz range was obtained by adjusting the seeder wavelength alone. The feasibility of this system for terahertz-wave absorption measurements over a wide frequency range was successfully demonstrated using low-pressure water vapor.","PeriodicalId":143116,"journal":{"name":"Proceedings, IEEE Tenth International Conference on Terahertz Electronics","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133415212","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}
