3. Consider an optical resonator made of two mirrors, one concave with radius of curvature R and a planar mirror. The separation d= R/2. Such a resonator is called hemispherical cavity. From the ray matrix formalism, calculate the condition for re-entrant rays, as we have done in class but for confocal cavity. - Points: 2

Problem 1: Fibre optics (2 points) Figure 1: Sketches of the geometry of an optical fibre A long cylinder of dielectric material can guide light via total internal reflection. This idea dates back to the 1870s and forms the basis of the modern fibre optics communication technology. As long as the diameter of these fibres is large compared to the wavelength of the infalling light, its wave nature is negligible and we can use Geometric Optics to study the propagation...

Graded-index plastic optical fibre (GI POF) is expected to be used for high- speed local area networks (LANS) because of its large core which allows for low cost and easy installation. A particular GI POF has a core diameter of 200um, a maximum core index of 1.500 and a numerical aperture of 0.30. 2.c.i 2.c.ii What is the maximum acceptance angle for this fibre?
