Abstract

We present the design and characterization of an improved YAG enhanced Silicon Avalanche Photodiode that is able to operate at high gain with low overall noise. The RAPD with active photon traps exhibits high Quantum Efficiency at 1064nm wavelength and a low capacitance.

Avalanche Photodiodes

manufactured by LASER COMPONENTS

UV-Sensitive Avalanche Photodiode for Optical Metrology Systems

Si APDs are suitable for the spectral range from 260 nm to 1100 nm.

Silicon avalanche photodiodes are used in the wavelength range from the UV to the near infrared. LASER COMPONENTS manufactures different series: highest quality for demanding systems, over customized version to components made for consumer products. Quick selection!

APD optimized for 1064 nm laser detection

Nd:YAG Enhanced APDs

Silicon APD for optical measurement and sensor systems

APD with excellent quantum efficiency made for photon counting.

The SAP-series silicon avalanche photodiodes are primarily used in photon counting. This series features highest efficiency and lowest dark current rates.

These APDs have a high sensitivity in the DUV/UV wavelength range.

The detector was developed specifically for (bio)medical applications in which the smallest signals in the short-wave UV/blue spectral range have to be detected.

APD in LCC Package for Compact Detection Modules

APD-arrays are now available from LASER COMPONENTS, enabling new applications in LIDAR and ACC.

Avalanche Photodiode for High-Speed and Low-Light Measurements

Best efficiency thanks to excellent signal-to-noise ratio.

The IAG series avalanche photodiodes feature a particularly good signal-to-noise ratio and support an amplification of more than 30. The inexpensive IAL series is made for consumer products.

Optoelectronic receiver with APD for fast detection applications

APDs with matched, integrated pre-amplifier in compact hermetic packages.

All receivers are available with Si or InGaAs APDs.
