Broadband 2 × 2 multimode interference coupler for mid-infrared wavelengths Stirling, Callum J. Halir, Robert Sánchez-Postigo, Alejandro Qu, Zhibo Reynolds, Jamie D. Soler Penadés, Jordi Murugan, Ganapathy Senthil Ortega-Moñux, Alejandro Wanguemert-Pérez, Juan Gonzalo Molina-Fernández, Íñigo Mashanovich, Goran Z. Nedeljkovic, Milos Circuitos integrados Beam splitters are core components of photonic integrated circuits and are often implemented with multimode interference couplers. While these devices offer high performance, their operational bandwidth is still restrictive for sensing applications in the mid-infrared wavelength range. Here we experimentally demonstrate a subwavelength-structured 2×2 multimode interference coupler with high performance in the 3.1−3.7µm range, doubling the bandwidth of a conventional device. 2024-09-26T17:51:22Z 2024-09-26T17:51:22Z 2024-09-26T17:51:22Z 2021-10-19 journal article Callum J.
