CMC Electronics Unveils New InGaAs Avalanche Photodiodes

CMC Electronics recently announced a significant advancement in their Optoelectronics line with the launch of the 767 Series Pigtailed High-Gain Low-Noise InGaAs Avalanche Photodiodes (APDs). This family of photodiodes is meticulously engineered to meet the demands of critical applications in detection, defense, and communication sectors, where precision and reliability are paramount.

Designed for Performance

The new series features high operating gains exceeding 100, making them ideal for various sophisticated applications such as Optical Time-Domain Reflectometry (OTDR), Distributed Temperature Sensing (DTS), and LiDAR. The combination of low noise and high gain allows these devices to function efficiently even in challenging conditions, ensuring accurate data collection and transmission.

Éric Desfonds, Senior Technical Applications Manager at CMC Electronics, emphasized, "Our APDs feature exceptionally low excess noise, enabling superior operating gain and dynamic range. This prevents issues related to unintentional Geiger mode operation, thus safeguarding device integrity."

Technical Specifications

The 276-339767-VAR model is available in variants tailored for single-mode and multi-mode fibers, boasting an active area of 30 µm and 80 µm, respectively. Key specifications include:

• - Quantum Efficiency: High efficiency across a wavelength range from 950 to 1600 nm.
• - Dynamic Range: Maintained even at elevated operating temperatures, significantly minimizing the need for cooling.
• - Excess Noise Figure: Features a very low excess noise factor (F), ensuring minimized noise interference.
• - Robust Operating Temperature: Effective performance across a broad temperature spectrum.
• - Connector Options: Available with FC/APC and SC/FC connector configurations.

With a coupling efficiency typically greater than 90%, these new APDs are engineered for flexibility and can cater to both standard COTS components and customized co-designs, ensuring that they can adapt to a range of specific application needs.

Significance in Modern Applications

Given the diverse sectors that benefit from high-performance photodiodes—from telecommunications and healthcare to industrial monitoring and defense—the introduction of the 767 Series underscores CMC Electronics' commitment to innovation and excellence.
