On road bikes, marketing is largely the reason for ubiquity in carbon forks. Most of the stock original equipment carbon forks aren't any lighter than aluminum, and they aren't carefully engineered to provide a better feel. But, they are carbon fiber, so they are perceived to be better. Nothing really wrong with them, but nothing compelling.
If you are going CF then make certain that you stay away from the lightest that are around, are built for performance or are not from a big name manufacturer that will warranty the fork for Tandem use. CF is the new wonder product and it is very easy to make a good looking product that is not made very well. And thgere are enough people around that will not pay out for the Best units made and will always go for something cheaper. Not only the Customer- some retailers do it aswell.
