• Response Range From 900 nm to 1700 nm
• Package Supports Single and Multi-Mode Fiber Coupling
• Both Small Area (High Speed) and Large Area
InGaAs photodiodes offer superb response from 900 nm to 1700 nm, perfect for telecom and near IR detection.
The 70 and 120 micron photodiodes are offered in isolated TO-46 packages with a lensed cap for single mode
and multi-mode fiber coupling. These two sizes are also available with actively aligned FC receptacles. The 70
micron photodiode is perfect for high bandwidth applications while the 120 micron photodiode is perfect for
active alignment applications. The 3 mm photodiode is isolated in a TO-5 package with a broadband double
sided AR-coated window. With the high shunt resistance, the 3 mm photodiode is suitable for high sensitivity
to weak signal applications.

Through the photovoltaic effect, detectors provide a means of transforming light energy to an electrical current.
The root of the theory behind this phenomenon is a small energy gap between the valence and conduction
bands of the detector. When light, with enough energy to excite an electron from the valence to the
conduction band, is incident upon the detector, the resulting accumulation of charge leads to a flow of current
in an external circuit. Since light is not the only source of energy that can excite an electron, detectors will have
some amount of current that is not representative of incident light. For example, fluctuations in thermal energy
can easily be mistaken for light intensity changes. A variety of these “non-light” contributions are present and,
when summed up, make up the total noise within the detector.
