Notes:
Electrical tuning of two-section quantum-cascade lasers is systematically investigated as a function of temperature and optical power. In pulsed operation, the active region design exhibits a low threshold current density (5.2 kA/cm2), a high peak (100 mW), and average (3 mW) powers at 300 K. The strong linear Stark tuning of the laser transition allows large tuning ranges of 40 cm−1, corresponding to a wavelength tune from 9.75 to 10.15 μm at 260 K for a peak optical output power of 10 mW. The tuning range is still 20 cm−1 at the same optical output power at T=300 K. © 1999 American Institute of Physics.
