Résumé
We report on a quantum cascade detector based on nearly strain compensated InGaAs/InAlAs pseudomorphically grown on InP substrate and detecting light at short wavelengths around 4 <i>µ</i>m. The background limited infrared performance (BLIP) condition is met at a temperature of 108 K with a high detectivity of <i>D</i><sup>*</sup><sub>BLIP</sub> =1.2×10<sup>11</sup> Jones.
