Bring to boil; cook for 5 minutes or until reduced by half. Stir in cream. Cook, uncovered, 8 minutes longer or until sauce is reduced. Drain pasta; toss with sauce.
Preheat oven to 375 F. In a large skillet with high heat, add olive oil. Season the salmon with salt and pepper. Pan sear the salmon skin side up for about one minute and cook the other side for another minute. Set aside on a baking sheet pan and leave in the preheated oven for about 5 minutes until medium done. DO NOT OVER COOK! Serve on top of the creamy pasta.
