Abstract

The laser drivers are extremely important to be used to provide safe interface for the optical components attached to the laser. In this paper, energy efficient laser driver circuit is design using field programming gate array (FPGA). The laser driver is first designed using current mode logic (CML) technique, which is widely used for designing the optical components. Then this design is implemented on FPGA using very large scale integration (VLSI). The laser driver produces the energy efficient output using voltage scaling technique in which the core voltage of FPGA virtex-7 board is reduced from 2.2 V (Peak core voltage of FPGA) to 0.5 V (base voltage of FPGA). By reducing core voltage of FPGA virtex-7 from peak to base voltage the power consume by laser drivers is reduced up to 90% for 15 THz frequency. Similarly, for less than 15 THz frequencies the power consumption is also reduced. The main advantage of designing this energy efficient laser driver is that it will control the output of any high frequency semiconductor laser up to 15 THz frequency. This energy efficient design of laser driver will be integrated with high frequency semiconductor laser to produce green optical output for communication systems.
