We show in this communication that photoconductors based on GaAs grown at low temperature can exhibit photoresponses as high as 25 mA/W under continuous-wave 1550-nm-wavelength illumination. It is achieved by using an optical Fabry-PÃ©rot cavity in order to improve the external quantum efficiency and by decreasing the post growth annealing temperature down-to 450 Â°C.
