[…] The objective of this PhD project is to demonstrate a new generation of photo-detectors with increased performance, thanks to the design of new types of antennas, and of new heterostructures with a stronger photoconductive gain by optimizing their quantum design. In particular, in the 8-12μm range, we aim for (i) an increase in responsivity by a factor of 2-3 compared to the state of the art; (ii) an extension of the 3dB RF bandwidth up to 200 GHz; (iii) the design of novel antenna architectures compatible with CMOS readout.
