Generation of cw THz electromagnetic waves by photomixing of two lights from independent two lasers had attracted a great deal of attention. However, each laser in the system should be stabilized separately, and a perfect spatial mode matching was required for efficient THz generation. Optical-alignment procedure is troublesome in practical uses. We report here a novel cw THz wave generation system using a two-longitudinal-mode laser diode (LD) in place of those complex or expensive light sources so far used. The two-longitudinal-mode LD used here radiated two coherent lights with their separation about 0.9THz, simultaneously from a single stripe.","PeriodicalId":344325,"journal":{"name":"1997 Digest of the IEEE/LEOS Summer Topical Meeting: Vertical-Cavity Lasers/Technologies for a Global Information Infrastructure/WDM Components Technology/Advanced Semiconductor Lasers and Application","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125696664","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}

This has the benefit of considering both the detailed bi-dimensional carrier behaviour at the Bragg-wavelength scale and the larger scale DFB effects such as the longitudinal spatial hole burning and the non-uniform current injection along the the laser cavity.","PeriodicalId":344325,"journal":{"name":"1997 Digest of the IEEE/LEOS Summer Topical Meeting: Vertical-Cavity Lasers/Technologies for a Global Information Infrastructure/WDM Components Technology/Advanced Semiconductor Lasers and Application","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129782334","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}
