TDBC microstructures made by local photo-bleaching in J-aggregate thin organic layers for photonics applications

Abstract

Tetrachlorodiethyl Benzimidazo Carbocyanine (TDBC) layers are very interesting for photonics applications due to their huge oscillator strength, narrow absorption, local photo-bleaching, and low-cost fabrication. They are mainly used in strong coupling studies, but also for light concentration, absorption enhancement, and so on. However, these intrinsic properties are still not very well understood and need to be investigated to fully exploit the high potential of this material, especially regarding the bleaching properties.
