The described effect takes place when the input beam is involved in nearly phase-matched third-harmonic generation. The nonlinear phase shift produced by this new cascaded nonlinearity is comparable to the nonlinear phase shift caused by the direct third-order nonlinearity x . A new analytical approach, low depletion approximation, was developed and used to study the cascaded third-order processes in the conditions of not very high third-harmonic conversion coefficients. At higher conversion coefficients the effect was studied by numerical simulations. The presence of a seeded thirdharmonic wave gives another possibility of controlling the additional phase shift of the fundamental wave. The conditions for stationary copropagation of the fundamental and the generated wave are presented. @S1050-2947 ~98!01004-X#","PeriodicalId":11780,"journal":{"name":"EQEC'96. 1996 European Quantum Electronic Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76376813","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}

In particular photonic band gaps may be used both to suppress [Z] and enhance [3] spontaneous emission. Recently we have studied band gaps for surface rather than bulk modes, and have shown that these may also be used to control spontaneous emission from a thin layer of dye 141. Such gaps occur when electromagnetic modes propagate on periodically modulated surfaces. We report on a detailed study to look at how the surface mode band structure depends on the surface profile. Our system comprised a corrugated metallic swfpce, fabricated using holographic techniques. Such a surface supports the propagation of surface plasmons. For M appropriate grating pitch Bragg scattering of the surface plasmon mode reds m the formation of a band gap. Using a convergent beam technique we are able to directly image the dispersion curve for the surface modes. With this technique we have determined how the band structure depends on the nature ofthe surface profile. The figure below shows how the width and central frequency of the gap valy as a hction of cormgation depth. The experimwtal data is seen to be well modelled by a recent theory [SI, indicated by the solid Line m the figures. The band gap described above only prohibits propagation over a small range of directions about the nod to the grating grooves. We have mersurcd how the band gap depends on the propagation direction and discuss the implications for the desiga of a photonic surface, ie one which prohibits the propagation of surface modes m all directions.","PeriodicalId":11780,"journal":{"name":"EQEC'96. 1996 European Quantum Electronic Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87894077","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}
