ABSTRACT:
An optical package arrangement is disclosed which is capable of reducing internal reflections while maintaining a common axis between the input device (for example, a laser diode) the output device (for example, an optical fiber) and various elements interposed therebetween. The output device is designed to include a bevel angle (.beta.) for redirecting reflections away from the common axis. In accordance with the teachings of the invention, an optical element (for example, an isolator, filter, window or any combination thereof) is inserted between the input and output devices and oriented at a tilt angle (.theta.) so that reflected signals from the element are also redirected away from the common axis. Focusing means disposed between the optical element and the output device is appropriately sized (in terms of focal length) so as to ensure maximum coupling of the signal into the output device along a beam entrance angle (.alpha.).
