Title:
MONOLITHIC ELECTRO-OPTICAL POLYMER INFRARED FOCAL PLANE ARRAY
Document Type and Number:
WIPO Patent Application WO/2012/087716
Kind Code:
A3
Abstract:
In one embodiment, a dual-band focal plane array includes a readout circuit (ROIC), and a plurality of electro-optical (EO) polymer pixels(218a,218b) for absorbing visible and/or short wave infrared (SWIR) radiation, each of the EO polymer pixels electrically coupled (208a,208b) to the ROIC. The detector further includes a plurality of microbolometers (302) for detecting long wave infrared (LWIR) radiation, each microbolometer electrically coupled to the ROIC via contact legs (224a,224b,224c) disposed between adjacent microbolometers and between adjacent EO polymer pixels. A method of fabricating a focal plane array (300) is also provided.
