The Specialized carbon handlebars that came on my Ruby are quite nice and you can get them separate. Many of my teammates favor FSA K-Wing bars, but if you need a smaller size than 40cm then they will be too big for you. Ritchey also makes some smaller (38cm) carbon bars that look quite nice (I've used their alu bars and liked them).

if you are looking for a carbon bar that has an "ergo-bend" in it, then I don't think you'll have any luck. Carbon just doesn't like to be formed into shapes like that I think.
