Abstract
In one embodiment, a dual-band focal plane array includes a readout circuit (ROIC), and a plurality of electro-optical (EO) polymer pixels for absorbing visible and/or short wave infrared (SWIR) radiation, each of the EO polymer pixels electrically coupled to the ROIC. The detector further includes a plurality of microbolometers for detecting long wave infrared (LWIR) radiation, each microbolometer electrically coupled to the ROIC via contact legs disposed between adjacent microbolometers and between adjacent EO polymer pixels. A method of fabricating a focal plane array is also provided.
