... No one has ever been able to define the difference between interference and diffraction satisfactorily … there is no specific, important physical difference between them … roughly speaking … when there are only a few sources, say two, interfering, then the result is usually called interference, but ...

Optical fibres
... There can be undesired reflection between transmitter lasers to the external modulator. To avoid the consequence as reflection this improves laser emission spectrum. Further, it causes quality deterioration which causes quality of transmission. To avoid above, a optical isolation is used across exte ...

Optical phase measurement emphasized
... Before any quantitative measurement, we can qualitatively show that there is indeed some optical phase change upon total internal reflection, which is revealed by modification of the polarization state. One can send a laser beam to a prism such that light is polarized at 45° with the horizontal. If ...
