Hollow-core photonic crystal (PCF) fibers filled with hot alkali vapor are a versatile platform for studying Rydberg physics at ambient temperature. In detail we discuss the possibility to use a Rydberg transition in rubidium to generate THz radiation. Previous work shows that even small hollow-core fibers can be rapidly and homogeneously filled with rubidium vapor [NJP, 24, 113017 (2022)]. Here, we excite the Rb atoms to the 17S1/2 Rydberg state, from where they decay with the highest probability to the 16P1/2 state, emitting during this atomic transition radiation at around 1.3 THz. The emitted light is expected to be narrowband and the wavelength can be tuned through the excitation scheme. To enhance the intensity of the generated THz radiation, the cell is nested in a tailored THz waveguide.
