Optic Version of the Mach-Zehnder Interferometer
Optic Version of the Mach-Zehnder Interferometer

... our fiber optic version we have replaced one beamsplitter and two mirrors by a bidirectional coupler supplied with single mode fibers. This replacement greatly simplified the operation of the interferometer. A stable interference pattern could quite easily be obtained. The simplified operation allow ...

Green's function formulation for third-harmonic generation microscopy

... Third-harmonic generation from an interface perpendicular to the optical axis was illustrated by Barad et al.7 With the Green’s function model we are able to investigate THG from interfaces of different orientations. Figure 4 shows that THG signals can arise from an interface perpendicular or parall ...

The structure may couple light into surface plasmon polaritons, SPPs, propagating along the metal semiconductor interface and eventually coupling with a ...

Not all of these materials diamond machine equally well. Several of metals can make optically “smooth”, and turn out to be good for diamond turning. They ar ...

Given the high powers involved, careful alignment this invisible laser was required, in part to ensure that the beam is safely contained while traversing a sequence of three mirrors, some of which are mounted to movable armatures controlled by ...

Since the refractive index ratio of the object with water is very small, the reflection and momentum changes are also small (less than 10% for either momentum formula). One may also ...

Applying this concept to STEM (Cowley 1969, Zeitler and Thomson 1970), it becomes clear that the STEM imaging optics (before the sample) are equivalent to the imaging optics (after the sample) in the conventional TEM (CTEM). Similarly, the detector plane in STEM plays a simi ...
