Scientific paper

High performance of InP-based quantum cascade lasers emitting at $\lambda$ ~
9$\mu$m are reported. Thick electroplated gold layer was deposited on top of
the laser to improve heat dissipation. With one facet high reflection coated,
the devices produce a maximum output power of 175mW at 40% duty cycle at room
temperature and continuous-wave operation up to 278K.
