To ensure output power levels and chirp performance similar to current DFB lasers with integrated electroabsorption (EA) modulators, a semiconductor optical amplifier (SOA) and an EA modulator are sometimes integrated with these arrays. We review the available data on uniformity, chirp and wavelength precision of these arrays, as well as the packaging requirements. An approach that separates a tunable wavelength source and the amplifier-modulator part into two different packages have also been suggested. For an SMS source, simultaneously modulated channels create significant cross talk penalties when propagating through a common SOA. However, without an SOA, a laser array with six directly modulated DFB lasers combined into a single output fiber, has been demonstrated.","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":"122756840","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}

One which can have a large impact, particularly on wavelength routed networks, is cross saturation, i.e. the dependence of the gain in any one channel on the total input power in all channels. When the number of wavelength channels in a saturated EDFA changes, the gain in the remaining channels also changes. The resulting power excursions in the surviving channels can degrade the system performance. Among the variety of methods used to prevent this problem is all-optical gain clamping. In this paper we present the results of a time- and spectrally-resolved simulation of two version of this all-optical stabilization method to examine some of the limitations of these techniques. The model assumes a completely homogeneous gain medium and a commercially available aluminosilicate fiber pumped at 1480 nm. We assume 2 input channels for the results presented, and we drop and add one of them. The numerical results are not necessarily optimized, but can be used to develop a quantitative understanding of the behavior of these amplifier chains.","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":"27 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":"125333157","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 paper describes, analyzes and provides preliminary data from a new three stage free space optical switch which utilizes VCSELs for the optical interconnections, a liquid crystal spatial light modulator (SLM) as a reconfigurable shutter and relatively simple optics for fan out and fan in. A custom CMOS chip is required to introduce a time delay in the optical bit stream and to drive the VCSELs. Analysis shows that the switch should be scaleable to 1024 input and output channels. This size switch requires an array of 2048 VCSELs.
