Optoelectronic device with integrated wavelength filtering
First Claim
1. An optoelectronic device including light energy converter means (1) adapted to transmit light waves to be processed to filter means (3) adapted to transmit a chosen spectral portion of the incident light waves and to reflect towards said converter means (1) a complementary spectral portion of said waves and reflector means (4) adapted to reflect the chosen spectral portion transmitted by the filter means towards said filter means (3), which device is characterized in that the filter means (3) are between the converter means (1) and the reflector means (4).

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.
