AI Technical Summary
DFB lasers experience mode hopping due to temperature changes during operation, resulting in output wavelength drift and optical power fluctuations, which affect the reliability of communication systems. Existing detection methods are expensive and cannot achieve online real-time monitoring, leading to low screening efficiency.
A heating resistor is installed on the DFB laser. A voltage signal is applied by a control device to raise the temperature of the heating resistor. The voltage signal is adjusted by a PID temperature control algorithm to keep the temperature of the DFB laser within a preset range, thereby reducing the risk of mode hopping.
It effectively reduces the risk of mode hopping in DFB lasers, improves the reliability of communication systems, simplifies the testing process, reduces costs, and enables online real-time monitoring.
