A method for reducing reflection of undesirable light in an opto-electronic package includes the coating of the interior surfaces of the package with light absorbing materials. Accordingly, when stray or scattered light is incident on package surfaces, reflections are minimized and therefore the optical noise, interference and feedback are reduced.
