Paving a Simpler Path to High-Power Terahertz Radiation

Coherent terahertz radiation has historically been very difficult to generate, and the search for an easy-to-use, compact source continues today.

Northwestern University researchers recently developed a simpler way to generate single-chip terahertz radiation — a discovery that...
