Although organic crystals present relevant linear and nonlinear optical features, studies on fs-laser processing in such materials are yet scarce. Thus, this work presents a study of the fs-laser incubation and damage threshold fluence determination in l-threonine crystals at 515 nm and 1030 nm. The damage threshold fluence was determined for one up to 105 pulses. For the single pulse regime, we obtained Fth = (0.94 ± 0.04) J/cm2 at 1030 nm and Fth = (0.31 ± 0.01) J/cm2 at 515 nm. Such difference is explained by the number of photons involved in each case; 5-photons at 1030 nm and 3-photons at 515 nm. Also, a slower incubation dynamic was observed at 515 nm. Still, micro-Raman spectroscopy revealed that no structural modifications were induced by the fs-laser pulses on the sample upon micromachining.

In this contribution, a systematic numerical study is made over the symmetry role of the 1D photonic structures (PhSs) containing a low number of slabs embedded in thin metal layers, in order to find the adequate conditions to enhance the quality factor of resonances and energy confinement in the subwavelength scale. We show the existence of single and double Tamm plasmon polaritons (TPPs) states according to the symmetry of the PhS, which allow to tune weak and strong coupling regimes with Metal–Insulator–Metal (MIM) platforms combined in a unique MIM-PhS-MIM structure. We found that while weak coupling is observable between MIM and PhS states at the PhS cavity mode wavelengths, strong coupling among the 2 MIMs and the PhS is obtained only at the TPP resonance wavelengths, exhibited by anti-crossing splittings at adequate insulator thicknesses. We found that for the double Tamm plasmon polaritons, the energy splitting can reach up to 134 meV, unlike the single TPPs where the maximum energy splitting is on the order of 50 meV. The degree of coupling was explained by the implementation of a variational method that exploits the analogy the optical superlattice herein proposed and an analogous superlattice quantum well. This article shows that TPP resonances are responsible for the coherent coupling between the two MIMs placed at a long distance given by the PhSs. Thus, these platforms provide an interesting and experimentally accessible route for the coupling of emitters in optoelectronic devices.</div>","PeriodicalId":52192,"journal":{"name":"Optical Materials: X","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49739007","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}
