It depends. As you get closer to the arctic circle, the shortest day of the year approaches zero length (although the twilight is still fairly bright due to atmospheric scattering), and as you go further north you have a longer and longer sequence of days where the sun doesn't rise. At the north pole itself, the sun slowly spirals down below the horizon for the full 6 months, but that's not in Alaska.
