Operation of type-II interband cascade lasers has been demonstrated in pulsed mode at room temperatures at wavelengths near 4.1 μm. These lasers fabricated with 150 μm wide mesa stripes also operated in cw mode at temperatures up to 145 K. Threshold current densities as low as 9 A/cm2 and output powers exceeding 100 mW/f have been achieved in cw mode at 80 K.
