Phlux Technology announces a 30 µm optical window version of the Aura family of 1550 nm Noiseless InGaAs APDs. The sensors, which are also available in 80 µm and 200 µm versions, are 12X more sensitive than traditional InGaAs APDs and have inherently fast impulse response and short diffusion tails. The new 30 µm version features lower capacitance at 0.15 to 0.4 pF, which increases the cut-off frequency to 3.5 GHz, compared to the 80 µm version a…
