Higher-order Tamm modes in nano-structured cap layers on a distributed Bragg reflector: Application for advanced optical sensing

Oumaima Haidar, Baptiste Mathmann, Yannick Dusch, Mohamed Boutghatin, Gaëtan Lévêque, El Houssaine El Boudouti, Abdellah Mir, Abdellatif Akjouj, Abdelkrim Talbi

Tamm modes, strongly confined between a metal and a distributed Bragg reflector (DBR), offer the advantage of being accessible with conventional excitation sources, without requiring coupling elements such as prisms. Here, we experimentally observe higher-order Tamm modes in such structures by…

Eman Abdel-Ghaffar, Amina Rezzouk, Fatima Houari, Soufyane Khattou, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani, Housni Al-Wahsh, Leonard Dobrzyński, Abdellatif Akjouj

This paper presents an analytical study of bound states in the continuum (BICs) in a photonic step-ladder waveguide structure. We demonstrate that BICs can arise in a cavity formed by one vertical and two horizontal waveguides inserted between two semi-infinite leads. Using the Green’s function…
