Towards Multimaterial Multifunctional Fibres that See, Hear, Sense and Communicate
... Although metallic mirror reflectors have been known for a long time and are attractive because they reflect light over a wide angular range, their usage in optics has been limited because of high optical losses. Multilayer interference filters, on the other hand, have low optical losses but exhibit ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
