Simple Single-Chip Circuit Heats/Cools Laser’s TEC (.PDF Download)

Nov. 10, 2015

A most critical device in an optical networking system is the laser diode, since it’s responsible for converting the electronic data to light pulses. This diode must be carefully controlled to stabilize the light output, and temperature is a key variable to determine the light’s wavelength. Thermoelectric coolers (TECs) are commonly used as part of this stabilization process. Since TECs come in many different power levels and have unique power requirements, a specific type of power supply is required to drive them properly...
