InGaAs Avalanche Pin Diode Photodetector 800-1700nm 50um 2GHz

The series avalanche photodiode is the commercial available InGaAs APD with high responsivity and extremely fast rise and fall times throughout the 900 to 1700 nm wavelength range.
The peak responsivity at1550 nm ideally suited to eye-safe range finding applications, laser radar, free space optical communications, optical fiber sensor, OTDR and high resolution Optical Coherence Tomography. The chip is hermetically sealed in a TO46 package.
