altNextreme Thermal Solutions (Durham, NC) has released a thin-film thermoelectric cooler module, the OptoCooler UPF40, designed for optoelectronic applications with high heat-flux requirements. The module is suitable for the cooling and temperature control of optoelectronic devices such as semiconductor optical amplifiers (SOA) and laser diodes. The OptoCooler UPF40 module can pump a heat density of up to 72 W/cm2 at 25°C, and as a result, it can move a maximum of 3.7W of heat with an active footprint of only 5.1mm2.
