Terahertz amplification by injection locking of waveguide resonant tunneling diode
James Greenberg, Brendan M. Heffernan, William F. McGrew +1
High power and low phase noise oscillators at terahertz frequencies are required for several burgeoning scientific and technological applications, including radioastronomy, imaging…
Dual-Wavelength Brillouin Lasers as compact Opto-Terahertz References for Low-Noise Microwave Synthesis
Scott C. Egbert, James Greenberg, Brendan M. Heffernan +2
Compact, ultra-low phase noise 10 GHz signals are essential for modern radar, coherent communications, and time-frequency metrology, especially with rising demands for additional s…
Terahertz molecular frequency references: theoretical analysis of optimal instability
W. F. McGrew, James Greenberg, Keisuke Nose +2
We report a comprehensive theoretical analysis of the instability achievable by using phase modulation spectroscopy to lock a terahertz local oscillator to an absorptive reference…
