Abstract

Developing tunable photodetectors that can operate over a wide range of wavelengths and integrating them into integrated circuits is a significant challenge in today's technology. These devices must be miniaturized, inexpensive, and easily manufactured. To address this challenge, we propose the development of a tunable planar hot-electron photodetector based on Tamm plasmon polariton. The tuning of the operational wavelength is achieved by incorporation of a material with a phase transition, Sb2S3, into Tamm plasmon polariton based structure. This allows for tuning of the detection wavelength over a broad range, encompassing all bands of the telecommunications spectrum.
