Nextreme has integrated its OptoCooler UPF4 thermoelectric cooler into Voxtel’s VDHAX line of hermetically-packaged avalanche photodiode (APD) receivers. The OptoCooler-equipped APD device will be used for applications in military laser radar and optical communications and commercial telecommunications. APDs can multiply the signal produced by incident light by as much as 100 million times, enabling photon detection at very low light levels. The APD device delivers more than 45°C of cooling during operation. The UPF4 removes a maximum of 610mW of heat at 85°C ambient in an active footprint of 0.55mm2.
