Fabricating campanile probes has been part science and part art, the scientists say, adding that the same applies to other nano-optical devices, such as microscopic lenses and beam splitters
. These devices require milling a 3D shape with sub-100-nm scale features on the tip of a wispy fiber, which is trickier than fabricating a nanostructure on a flat surface such as a wafer.
These off-diagonal elements are such that measuring the number of photons at the horizontal output port of the beam splitter
is affected by the result of detecting photons at the vertical port and vice versa.
In this case, when the two half-beams return to the beam splitter
, they are no longer in step and an interference pattern is produced
Knill, Laflamme and Milburn (KLM) (48) have shown that this obstacle can be overcome using linear optics, single photon sources, photon number detectors, and multi-photon interference at a beam splitter
For these reasons we implemented a directional beam splitter
(DBS) which separates beams by their propagation direction rather than by their wavelength .

Some people have tackled this problem by using a beam splitter
to share a telescope's field of view with the imaging camera and guiding system, but this robs the camera of valuable light.
After the lens, the beam was split into two sub-beams using a beam splitter

Zeiss interferometer (Figure 1) is based on Kosters design (Hariharan, 2003) which performs amplitude splitting of the source radiation (visible light in this case) by a beam splitter
which divides the incoming beam into two beams- reference and measurement beam.
