| Abstract | A photodiode pixel structure for imaging short wave infrared (SWIR) and visible light built in a planar structure and may be used for one dimensional and two dimensional photodiode arrays. The photodiode arrays may be hybridized to a read out integrated circuit (ROIC), for example, a silicon complementary metal-oxide-semiconductor (CMOS) circuit. The photodiode in each pixel is buried under the surface and does not directly contact the ROIC amplification circuit. Disconnecting the photodiode from the ROIC amplification circuit enables low dark current as well as double correlated sampling in the pixel. |
