Fig. 3. Performance characteristics of the photoconductive detector at room temperature.

Fig. 3

(A) Responsivity as a function of applied bias over four IR spectral regions. (B) JOLI D* and BLIP D*. (C) Photoconductive polymer response (blue) and a commercial InGaAs photodiode response substituted for the polymer (red) toward a train of femtosecond laser pulses (1550 nm, 1 kHz, 150 fs). (D) (Top) Expansion of a single femtosecond detector transient and a single exponential fit (red) gives a 10 to 90% rise time of 115 μs and a decay constant of 109 μs. (Bottom) Bode plot of the photoconductive detector showing a −3 dB bandwidth of 1.6 kHz.
