The advantage of this method in comparison to the conventional finite-difference time domain (FDTD) technique is that it computes Greens function of the photonic structure recursively by adding slice by slice on the basis of Dyson equation. In the present work a detailed study of the surface modes residing on a termination of a photonic crystal with a corrugated boundary is conducted. A particular attention has been paid to the effect of surface modes on the performance of a lasing cavity defined in a band-gap photonic structure. Based on the developed recursive Greens function technique we calculate a Q factor of a cavity situated in the crystal in the vicinity of a photonic structure termination","PeriodicalId":354643,"journal":{"name":"CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005.","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133297097","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}

The FOPA comprises a typical configuration, in which signal and pump are semiconductor lasers. It can be theoretically shown that both cross-phase modulation (XPM) and parametric amplification can cause the signal polarization change with pump power. It is important to note that, if two orthogonally polarized signals are inserted into the FOPA, any source of birefringence will maintain their orthogonality while the parametric gain will tend to make their polarization parallel","PeriodicalId":354643,"journal":{"name":"CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005.","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122372302","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}
