Paper Abstract

The laser drive is one of the key components needed to generate the high-current, high-speed signal required for driving a transmitter, This paper propose a novel parallel laser drive circuit model with adaptive bandwidth bus architecture based on hybrid current/voltage mode. By using the highly parallel characteristics of the VCSEL and the bus structure, the system becomes very compactable. Several improvements can be achieved in signalling speed by using current mode in comparison to voltage mode. Therefore we use the current mode control module. By using the on hybrid current/voltage mode in the data path, the static power dissipation is reduced greatly when the data path is idle. Overall power dissipation improvement is attained over voltage-mode signalling schemes at high data rates while minimizing the power dissipation.
