Photonics West Session to Explore DTP Size, Weight, Power and Cost Benefits

We’re excited to announce that our Chief Technology Officer, Doug Crane, PhD, will be speaking at this year’s Photonics West conference in San Francisco. His talk, "Path to higher SWaP-C for cooled IR through thermoelectrics with distributed transport properties," will take place on Monday, January 24 from 2:40–3:00 PM PST in Room 202 (Level 2 South).

Improving SWaP-C With DTP

During his session, Dr. Crane will delve into the size, weight, power and cost (SWaP-C) benefits of our distributed transport properties (DTP) approach to thermoelectric (TE) material systems. Without any moving parts, TE coolers are solid-state heat pump systems that use electric power to cool, achieving a small size, light weight, low cost, vibration-free operation, excellent durability and more. Conventional TE (CTE) material systems, on the other hand, are limited in their ability to cool quantum infrared detectors to low operating temperatures required by high-performance systems. They also have lower cooling capacity compared to DTP material systems.

Our studies show that DTP technology can significantly improve the capabilities of TE systems, resulting in practical, inexpensive, lightweight and highly reliable deep-cooling systems and enabling a new class of deep-cooled infrared sensors. In addition to these points:

  • It is possible to create a single-stage TE device operating in cooling mode with a maximum temperature differential that exceeds advanced CTE systems by 35 percent.
  • At high-temperature differentials, the coefficient of performance (CoP) and cooling power of these devices increase to more than 150 and 200 percent, respectively.
  • DTP TE devices offer superior performance under all operating conditions.
  • In multi-stage devices, DTP technology can achieve the large temperature differentials necessary to provide deep cooling and temperature control to quantum infrared sensors.
