Silicon quadrature photodiodes

Silicon quadrature photodiodes with high sensitivity in the 400- to 1100-nm range are available as chips or in TO-8, custom, or ceramic packages. The chips are available in either round (0.250-in. diameter) or square (0.250 × 0.250 in.) versions. The gap between segments is 0.002 in. Dark current and crosstalk are both less than 1 nA.
