The InGaAs detector is housed in a TO-5 package with an anode, cathode and case connection. 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 (RLOAD) from the photodiode anode to the circuit ground. The output v...
