Abstract

Narrow stripe-width, low-ridge quantum cascade lasers operating at 5.3 μm were fabricated from InP-based, metal-organic chemical-vapor-deposition- grown material. Maximum peak-pulsed output power of 12 W at 14 A was measured from a low-ridge laser with a high reflectivity coated back facet. Modeling shows that the lateral variation of the transverse conductivity is essential for an accurate description of the current spreading in these devices.
