The InGaAs Avalanche Photodiode product family from Excelitas features active area sizes ranging from 30 µm to 200 µm, catering to various applications requiring photonic detection between 1000 nm and 1700 nm. The C30645, C30662, and C30733 series of avalanche photodiodes (APDs) are high-speed, high-gain devices made from InGaAs/InP. They offer high quantum efficiency (QE), high responsivity, and low noise within the 1000 nm to 1700 nm spectral range, with optimization at 1300 nm and 1550 nm wavelengths. An enhanced low-noise option for the C30645 and C30662 APD series enables OEMs to achieve advanced noise specifications and optimal signal-to-noise ratios (SNRs). This enhancement increases the detection range using the same laser output power, making it ideal for eye-safe range-finding and LiDAR systems. With a gain of up to 100, the C30733 series sets a new standard for detecting low light intensity fluctuations, essential for advanced Optical Time-Domain Reflectometer (OTDR) systems and other applications.
