FIGURE 1. Operating principle of a thermoelectric cooler based on the Peltier effect: When current flows through the semiconductor elements between ceramic substrates, heat is absorbed at the cold side and rejected at the hot side to create a controlled temperature differential across the device.
Thermoelectric coolers provide precision temperature control for lasers, detectors, and integrated photonics—where addressing thermal drift at the device level is essential.

Scintil’s LEAF Light addresses the fabric bottleneck in AI clusters by integrating multiple DWDM laser channels onto a single chip. Increasing bandwidth per fiber instead of fiber count enables higher edge bandwidth density and improved energy efficiency within copackaged optical architectures.
