Description

The Thorlabs FGA01FC InGaAs High Speed Photodiode is ideal for measuring both pulsed and CW fiber light sources, by converting the optical power to an electrical current. The detector is housed in a TO-46 (mod) package with an anode, cathode, and case connection and mounted in an FC bulkhead connector. The photodiode anode produces a current, which is a function of the incident light power and the wavelength. The responsivity ℜ(λ), can be read from Figure 1 to estimate the amount of photocurrent to expect. This can be converted to a voltage by placing a load resistor R(L) from the photodiode anode to the circuit ground.

The bandwidth, fBW, and the rise time response, tR, are determined from the diode capacitance, CJ, and the load resistance, R(L)L, as shown below. The diode capacitance can be lowered by placing a bias voltage from the photodiode cathode to the circuit ground.
