The single mode fibers do not exhibit intermodal dispersion (which will be discussed in Chapter 3), thus the light pulse reaches the end of the fiber only slightly distorted. Therefore, the single mode fiber is suitable for long-distance transmission since the ...

... The problems of this assignment deal with optical resonators and laser light. You do not need to know the physics of how a laser works, but you need to assume the following: (i) Only a single longitudinal and transverse mode of the cavity will be occupied with light. (ii) One of the mirrors is just ...

Optical aberration
.svg?width=300)
An optical aberration is a departure of the performance of an optical system from the predictions of paraxial optics. In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system. Aberrations occur because the simple paraxial theory is not a completely accurate model of the effect of an optical system on light, rather than due to flaws in the optical elements.Aberration leads to blurring of the image produced by an image-forming optical system. Makers of optical instruments need to correct optical systems to compensate for aberration.The articles on reflection, refraction and caustics discuss the general features of reflected and refracted rays.
