Their low threshold current, circular beam, and excellent temperature stability are advantageous for many applications. While excellent lifetimes have been reported, lower early failure rates at high temperatures and high powers would be desirable, so we seek to better understand the aging process. Our past work has shown that dislocations grow not only in the active region (as expected) but also in the p-DBR. We have proposed that high-energy spontaneous emission from the active region is a driving force for degradation in the p-mirror layers. In the past year, we have been concentrating on developing new techniques to allow us to examine the VCSELs in plan view, and explore the radial extent of the degradation.","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":"88 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":"122585384","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}

Due to their unique multi-wavelength operation capability simplified architectures of optical cross-connects and add-drop nodes can be realized. By fabricating these devices in erbium-diffusion doped LiNbO/sub 3/ internal amplification can be added by optical pumping. Moreover, by optical feedback in a cavity even lasing can be achieved with a tunable emission wavelength.

The SOA-fiber-grating wavelength converter uses a single amplifier and requires no interferometers. The principle of this device is described as follows: Consider an input pump beam at /spl lambda//sub 1/ and a CW probing signal at /spl lambda//sub 2/ coincident in the amplifier. The pump beam partially depletes the gain of the amplifier. This rapidly increases the refractive index of the semiconductor and chirps the CW signal at /spl lambda//sub 1/ towards the red, There is a smaller, blue chirp associated with the slower recovery of the amplifier's gain. The probing signal's wavelength, /spl lambda//sub 2/, is adjusted such that the fiber grating passes the red chirped portion of the CW signal and blocks its unchanged spectral components. We use a more compact, fiber grating step filter than previous devices which selects the phase modulated portions of the probing signal more effectively.","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":"10 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":"121766955","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}
