Thaw salmon if frozen. Rinse salmon; pat dry with paper towels. Set aside. Preheat the oven to 425 degrees F. In a 15x10x1-inch baking pan combine sweet pepper pieces and tomatoes. Drizzle with olive oil and sprinkle with half of the rosemary, the salt, and black pepper. Toss to coat. Roast, uncovered, for 20 minutes.
Meanwhile, cook pasta according to package directions; drain and keep warm.
Remove pan from oven. Stir wine and balsamic vinegar into vegetable mixture. Add salmon pieces to pan and turn to coat with wine mixture. Return to oven and roast about 10 minutes more or until salmon flakes easily when tested with a fork.
To serve, divide pasta among four plates. Top pasta with vegetable mixture and sprinkle with basil. Place salmon on vegetables and sprinkle with remaining rosemary.
