This index-guide is created by a dip in the carrier concentration between the stripes. The first lasing mode of a twin-stripe array, having 4-μm wide stripes with a 8-μm center-to-center spacing, is the zeroth-order index-guided mode. This mode has been identified by a single-lobed far field and a near-field profile tightly confined between the stripes. At higher currents, a double-lobed near-field intensity profile is observed to lase simultaneously at a 10-20-Å wavelength shorter than the wavelength of the fundamental. Although the far field is double-lobed, suggestive of an out-of-phase gain-guided array mode, careful measurements of the near field indicate that this double-lobed mode is the first-order index-guided lateral mode. The small lateral extent beyond the stripes in the near field and the lack of interference fringes between the stripes is inconsistent with a gain-guided super-mode.","PeriodicalId":428080,"journal":{"name":"Conference Proceedings LEOS Lasers and Electro-Optics Society","volume":"2512 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131318964","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}
