INTEGRIERTE OPTOELEKTRONISCHE VORRICHTUNG ZUM FILTERN VON WELLELÄNGEN

摘要

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 (d 1 ) 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 (d 2 ) 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.
