A device including a first portion, a second portion, a first contact and a second contact, the first portion being made of a semiconductor having a first doping, the second portion being made of a semiconductor having a second doping different than the first, the first portion and the second portion forming a p/n junction including a depletion zone in the first portion, the contacts being configured so that when an electric voltage (V) is applied between the contacts, a dimension of the depletion zone depends on a value of the electric voltage, an ionization energy being defined for dopants of the second portion. The device includes an emitter generating a radiation having an energy greater than the ionization energy and illuminating the second portion with the radiation.
