Patent ID: 6927387

Claim:
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 ); wherein said converter means ( 1 ) are at a first distance (d 1 ) from the filter means ( 3 ) chosen so that the waves that they transmit and the complementary spectral portion reflected by said filter means ( 3 ) create a first standing wave whose associated electric field has a node in said converter means ( 1 ) and at a second distance (d 2 ) from the reflector means ( 4 ) chosen so that the chosen spectral portion and the chosen spectral portion reflected by said reflector means ( 4 ) create a second standing wave whose associated electrical field has an antinode in said converter means.
