Tunable Tamm plasmon polariton based planar hot-electron photodetector from O- to U-band

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. Operational wavelength tuning is achieved by incorporating a material with a phase transition, Sb2S3, into a Tamm plasmon-polariton-based structure. This allows for tuning the detection wavelength over a broad range encompassing all bands of the telecommunications spectrum.
