Abstract

Abstract : In article number1900460, Hua Li, Juncheng Cao, Kai Zhang, Heping Zeng, and co‐workers report a graphene‐based approach for enhanced passive frequency comb operation and pulse generation in terahertz semiconductor lasers. The saturable absorption and group velocity dispersion compensation provided by a multi‐layer graphene sample result in a laser frequency comb operation with highly stabilized frequency lines and optical pulse generation (16 ps) in the terahertz regime.
