| Summary: | In optical communication systems, semiconductor lasers are widely in use as an optical source but the performance of
laser are limited due to temperature variation, design incompetency, and power consumption issues. The direct output of
semiconductor laser may destroy the additional component attached in the system. In this research, semiconductor laser,
driver is implemented by utilizing the current mode logic technique to control the output of semiconductor laser. Current
Mode Logic (CML) is one of the compatible technique to work integeratedly with optical components. CML based design
of semiconductor laser driver has achieved the current ranges from 5.6 mA to 6.8 mA and efficiently working up to 10 GHz
frequency and consume 75% less power than typically available laser drivers. In future, the semiconductor laser may have
implemented using System on Chip (SoC) configuration to make the design more energy efficient, in terms of temperature
sensitivity and power consumption. |
