This is done using a delay differential equation model to calculate bifurcation diagrams in the plane of the feedback parameters. We find an increased complexity in the dynamics of the laser when the effective α-factors of the gain and absorber sections are different. With non-zero α-factors, quasiperiodic mode-locking can also be induced by resonant feedback and the extent of complex dynamical regions in the parameter plane increases.","PeriodicalId":114800,"journal":{"name":"Numerical Simulation of Optoelectronic Devices, 2014","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124859586","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}

We investigate the differential equations of the case of an oblong rectangular photodiode with significant sheet resistance of one electrode.
