Abstract
The invention relates to an optoelectronic device including filter means (3) for transmitting a selected spectral portion of light waves and for reflecting a complementary spectral portion thereof, placed between means (4) for reflecting the chosen spectral portion towards the filter means and converter means (1) for transmitting the light waves to be filtered to the filter means. The converter means are at a first distance (d1) from the filter means chosen so that the waves that they transmit to them and the reflected complementary spectral portion create a first standing wave whose associated electric field has a node in the converter means (1) and at a second distance (d2) from the chosen reflector means so that the chosen spectral portion and the chosen and reflected spectral portion create a second standing wave whose associated electric field has an antinode in the converter means.
