[/free]Designs of infrared non-polarizing beam splitters
When used at oblique angles of incidence, the re?ectance and transmittance of thin ?lms exhibit strong polarization effects(PEs), particularly for the ?lms inside a glass cube, which result from the fact that the tangential components of the electricand magnetic ?elds are continuous across each layer interface. However, for many applications, the PEs are undesirable andshould be reduced. Therefore, the concept of non-polarizing beam splitter (NPBS) is proposed. Up till now, however, mostof the reports of NPBSs are suitable for visible light. Therefore, it is necessary to ?nd out some methods to reduce the PEsfor infrared applications. A design method of the infrared NPBS in a cube is proposed, the theoretical analysis is given,designs for different substrates are demonstrated and the simulations of their optical properties are presented in thispaper.r 2005 Elsevier Ltd.
