There have been several breakthroughs in terahertz science and technology. Major recent advances have brought novel avenues for terahertz generation to the limelight. Research work pertaining to terahertz generation and its applications has expanded at an unprecedented rate. This encompassing review provides a detailed description of current means of terahertz generation with a special focus on optical sources. Finally, a specific recent development utilizing a novel dual-wavelength, C-band, SOA-based, fiber hybrid compound-ring resonator source is discussed. Boasting both single and dual-port operation, this source is utilized to excite a terahertz photo-mixer and achieves a difference wavelength tuning range of 20.42 nm (i.e., 2.51 THz) which corresponds to a terahertz radiation range of 0.8–2.51 THz at room temperature.
