Spectral gain narrowing in THz Quantum Cascade Lasers above laser threshold using THz-time domain spectroscopy

Not Accessible

Your library or personal account may give you access

Abstract

Terahertz time-domain spectroscopy is used to determine the gain of terahertz quantum-cascade lasers. Gain clamping and spectral gain narrowing are observed above threshold, giving insight into subband alignment as a function of the applied voltage.
