Patent ID: 7719029

Claim:
An article comprising a first detector that is characterized by a first RC time constant, wherein the first detector comprises: a first photodiode for producing a first electrical signal in response to receipt of a single photon that has a wavelength greater than 1000 nm, wherein the first photodiode has a first doped region that has a first perimeter, and wherein the first photodiode is characterized by a first photodiode capacitance, C p1 ; and a first thin-film resistor; wherein the first thin-film resistor and the first photodiode are electrically connected and monolithically integrated such that (1) the first thin-film resistor is disposed above the first doped region and located substantially completely within the first perimeter and (2) the effect of the integration of the first thin-film resistor on the first RC time constant is less than approximately 5%.
