| 总结: | In this paper, green hybrid silicon semiconductor (HSS) laser driver is designed using voltage scaling techniques. Voltage
scaling is very popular approach for reducing total power of integrated circuits. The HSS laser driver is designed using
current mode logic (CML) technique, which is widely used technique for designing optical components. CML technique
provides the strength to the laser driver for high frequencies mid-range infrared range. The HSS laser driver firstly, is
developed in Matlab that consume very high power. After that, the HSS laser driver design is implemented on FPGA virtex-6
family, package FF784, XC6VCX75T device at speed of -2 using voltage scaling technique. The HSS laser driver is operated
at different mid infrared range frequencies on Matlab based model and FPGA model. It is concluded that using voltage scale
technique on FPGA, power optimization is performed for the HSS laser driver. In results for different mid-range infrared
frequencies more than 95% power is saved by comparing the power consumption of Matlab based model and poweroptimized
model using voltage scaling on FPGA. This energy efficient design of semiconductor laser can be integrated with
other optical components to make optical communication system green. |
