<p>A method for detecting wavelengths within a predefined range by a photodetector and a photodetector for carrying out the method, wherein transition of electron energy is performed by absorption of energy in response to an incident light, such that said transition is performed in intra-band within a quantum well (1), between quantized levels (E1, E2) in a conduction band (12). The free electron generated by said transition are then subjected to multiplication in an avalanche layer (3).</p> |
