Abstract
In various embodiments, an optical alignment structure may be provided. The optical alignment structure may include a light carrying structure configured to receive an input optical light from an external light source. The optical alignment structure may further include a light redirection mechanism coupled to the light carrying structure. The light redirection mechanism may be configured to receive the input optical light from the light carrying structure. The light redirection mechanism may be further configured to redirect the input optical light back to the light carrying structure, the redirected input optical light configured to be detected by a detector for alignment of the optical alignment structure with the external optical source.
