For decades the terahertz (THz) region of the electromagnetic spectrum (roughly 300GHz-3THz) has intrigued researchers with its potential to enable faster wireless communications, ultrahigh-resolution spectroscopy and more precise sensing. Yet, despite a solid understanding of the underlying physics, real-world THz systems have remained elusive. A major challenge has been the lack of THz sources capable of delivering both the output power and spectral purity required for practical applications. That may be starting to change. Researchers at IMRA America have demonstrated a new THz source architecture that overcomes several long-standing limitations. The broadband hybrid circulator IMRA applied was developed by Micro Harmonics. Read the full article here.
