Description
The Thorlabs FDS010 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-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 (λ), can be read from the responsivity
graph to estimate the amount of photocurrent to expect. This can be converted to a voltage by placing a load
resistor (RL) from the photodiode anode to the circuit ground. The output voltage is derived as:
The bandwidth, fBW, and the rise time response, tR, are determined from the diode capacitance, CJ, and the
load resistance, RL, as shown below. Placing a bias voltage from the photo diode cathode to the circuit ground
can lower the photo diode capacitance.

Application of a reverse bias can greatly improve the response speed and linearity of the device. This is due to
increase in the depletion region width and, consequently, decrease in junction capacitance. However, the dark
current and noise will increase.

Graphs
The responsivity of a photodiode is a measure of its sensitivity to light, and it is defined as the ratio of the
photocurrent IP to the incident light power P at a given wavelength:
In other words, it is a measure of the effectiveness of the conversion of light power into electrical current.
Responsivity varies from lot to lot and with the wavelength of the incident light, applied reverse bias, and
temperature. It increases slightly with applied reverse bias due to improved charge collection efficiency in the
photodiode. The change in temperature increases or decreases the width of the band gap and varies inversely
with the temperature.
