Could I use the ADN2848 Laser Diode Driver in parallel?

Hi, I am trying to directly module a laser diode with Ibias = 80mA and Imod up to 600mA, with inputs varying up to 1Ghz. I trying to build a transmitter and the information signal directly modulates the laser drive current and hence the optical carrier. The modulation schemes is on-off keying (OOK) . Now, my question is: Could I use the ADN2848 Laser Diode Driver in parallel? How many I can use in parallel? 

Please revert back to me with, options, and another suitable alternatives solutions.
 
We would appreciate very much your support.
