Abstract
A method and apparatus are provided for transmitting an optical communications signal. The method includes the steps of securing an optical device onto an optically transparent substrate with an optically transparent adhesive such that an axis of transmission of the optical device passes directly through the optically transparent adhesive and a portion of the body of the optically transparent substrate, darkening a portion of the optically transparent adhesive with a laser; and transmitting light from the optical device through the darkened portion of the optically transparent adhesive such that at least some of the light from the optical device is absorbed by the darkened portion.
