Drive electo-optic modulators with FPGA
While I may have misunderstood your drive requirements, a MOSFET gate driver would seem to be a good place to start. TI makes a line http://www.ti.com/lsds/ti/power-management/gate-driver-products.page#p9=3.2;5.3&amp;p528=4;6&amp;p529=12;14&amp;p248=1;7.6&amp;p598=TTL and a UCC27611 seems a decent choice. 5 nsec rise and fall times, and 10 volts into 50 ohms is .2 amps, while the IC will do .3 amps average. It comes in a very small package, too. And lots of other manufacturers make something similar, so I'm not specifically recommending this one, just using it as an example.
