By adjusting the ridge waveguide and grating period (?), the fundamental modes and one-order lateral mode can exist in a narrow ridge waveguide. The related frequency is about 0.65 to 0.7 THz. © 2021 IEEE.[SDGs]SDG3Distributed feedback lasers; Terahertz waves; Continuous-wave terahertz; Distributed-feedback laser; Dual modes; Fundamental modes; Grating periods; Lateral modes; Longitudinal modes; Monolithics; Terahertz generation; Ridge waveguidesconference paper10.1109/ISLC51662.2021.96158982-s2.0-85122889335
