Amplification Technologies Announces New Eye-Safe Fiberized Discrete Amplification Photon Detector for 3D LiDAR Applications

LINDEN, N.J., Jan. 24, 2020 (GLOBE NEWSWIRE) -- Amplification Technologies Corp. (“ATC”) announces today the availability of a new variant of its Discrete Amplification Photon Detector (DAPD) Negative-feedback Geiger mode avalanche photodiode for 3D LiDAR and other applications: a Fiberized-DAPD. ATC’s Fiberized-DAPD offers single-photon level detection ability, wide dynamic range, a large linearity range, and an extremely high repetition rate of up to 100MHz. In addition, the Fiberized-DAPD can operate in an always-on mode with fast response. The Fiberized-DAPD uses discrete amplification, which monolithically integrates a negative feedback circuit within the photodetector to create very high sensitivity.

We offer the Fiberized-DAPD as a module that includes a pre-amplifier, or as a stand-alone photodetector in a T08 package. The module simplifies evaluation and facilitates integration with analog to digital conversion systems and subsequent digital signal processing. The TO8 includes an active thermo-electric cooler that is capable of cooling the DAPD sensor to ­50⁰C. The fiber coupled to the DAPD is multi-mode with a 200 micron core, terminated with a FC flat-polished connector with anti-reflection coating. The Fiberized-DAPD provides several benefits in comparison to free-space optics configurations:

• Heat management, to cool the TEC and hence the DAPD
• Ease of building signal processing electronics outside of the optical apparatus
• Optical isolation in LiDAR applications, so the laser pulse won’t trigger a response because of reflections from the LiDAR encapsulation

Key product features and their importance for real-time 3D imaging:

950nm to 1650nm wavelength range:
These detectors operate in the eye-safe range (unlike the combination of a silicon detector and a GaAs laser).

High sensitivity, up to single photon level:
The Fiberized-DAPD features high sensitivity and a wide dynamic range to address these requirements.

Wide dynamic range and ability to detect various grey levels:
The Fiberized-DAPD wide dynamic range significantly enhances the ability to identify and distinguish between different objects, especially in poor weather conditions.

High repetition rate throughput:
The high throughput improves to available signal to noise: more signals can be transmitted and received at a given time, to generate more data.  In addition this facilitates the use of error correction algorithms.
