Abstract

Electromagnetically induced transparency (EIT) is a phenomenon where a narrow transparency window appears within an absorption band of a material due to quantum interference. This effect has significant applications in various fields, including slow light devices, optical filters, and sensors. This paper compares three prominent EIT implementation resonator structures: single direct-coupled, double coupler add-drop, standard double resonator (SDR), coupled ring reflector (CRR) and self-coupled optical waveguide (SCOW). We analyze their underlying mechanisms, performance characteristics, and suitability for different applications, supported by recent research from 2020 onwards. We also present simulated transmission spectra, using Lumerical Interconnect, for each configuration to visually illustrate their distinct features.
