This application note first briefly discusses the basic operation theory of a thermoelectric cooler (TEC) and its application in optical modules. Then it presents a digital approach to TEC control ...

Opto-electronic systems frequently require temperature stabilization for components such as laser diodes, photodiodes, prisms, and lenses. The established method for providing stabilization is to ...

Laser diodes are used in fiber-optical telecommunication systems as transmitter lasers for sending signals, pump lasers for erbium doped fiber amplifiers (EDFA), and semiconductor optical amplifiers ...

Controller IC combines power management and mixed-signal functions that implement adaptive control of closed loop compensation. This SoC consists of a DSP and RISC processor, RAM and non-volatile ...
