DEPHAN is a developer of next-generation photodetectors with outstanding technical performance.

Why photodetectors?

Photodetectors are the key element for many rapidly growing applications and markets:

  • Automotive LiDAR Industry
  • Medical Equipment
  • Spectrophotometry
  • Optical communication
  • and many others

Existing technologies are a performance bottleneck for LIDAR market players.

DEPHAN has designed a device that eliminates the drawbacks of first-generation automotive LiDARs and finally enables building automotive LiDAR devices fit for mass adoption which are long-range, high-resolution and affordable.


Thus, DEPHAN technology perfectly matches the needs of next-gen LiDAR developers. Our samples are already being tested by several international companies and have received positive feedback. Our portfolio of international partnership is constantly growing.

In 2020 DEPHAN is aiming to attract a new round of investments and launch mass production of photodetectors for the LIDAR market as well as start pre-product lot development for optical communications and bio-med markets.

Applications

Replacement of vacuum photomultipliers (PMTs) with a solid-state – one of the DEPHAN’s goals.

Based on design potential and the first positive results of testing the DEPHAN pilot prototypes we can expect following applications:

LiDARs

Medical Equipment

Biotechnology

Industrial Measurement

Free-Space Communication

Spectrophotometry

Aerospace Applications

Drones

Timeline

Earlier…

1990s

The two principal technical solutions proposed and realized by the authors of the project Dr. Shubin and Dr. Shushakov in the middle of the 1990s made it possible to solve the ultimate problem of signal detection: analog detection with single-electron sensitivity threshold. The first one is effect of self-calibration of current cord provoked by a single electron in avalanche structure with negative feedback in conditions of above-critical voltage. This effect allows one to realize a single-electron threshold amplifier with high response probability and stable calibrated output signal. The second is utilization of avalanche structure with negative feedback in the above-critical “Geiger” mode and merging output signals emerging from such structure of threshold single electron amplifiers for the purpose of analog signals detection.

Beginning of 2000

Since the beginning of 2000s the research group under supervision of Dr. Shubin develops alternative to conventional SiPMs approach to design of multicell solid-state photomultipliers with wide dynamic range.
