SELF-MODE-LOCKING QUANTUM CASCADE LASER |
摘要 |
A self mode-locking (SML) mid-infrared (5 and 8 .mu.m) quantum cascade laser is formed that comprises both a relatively thin dielectric insulating layer (i.e., less than one-half micron in thickness) overlaid with an optically highly lossy (i.e., absorbing) layer, with a relatively long (approximately 3.5 mm) optical waveguide. Evidence of mode-locking is obtained from the measured optical spectra and corresponding interferograms, as well as from the rf spectra of the photocurrent detected with a fast quantum-well infrared photodetector. A n estimate for the pulse width of approximately 3 psec is inferred from these data.
