PPT-Phys 102 – Lecture 17 Introduction to ray optics

1 Physics 102 lectures on light Lecture 15 EM waves Lecture 16 Polarization Lecture 22 amp 23 Interference amp diffraction Lecture 17 Introduction to ray optics Lecture . Here we first develop the basic understanding of the directional coupler and then we will study its implementation in an integrated form The directional coupler consists of two channel optical waveguides placed close to each other so that their fiel They can various functions like phase amplitude and polarization modulation and also wavelength filters The main material which made these devices possible is Lithium Niobate LiNbO3 In the early optical systems where the data rate was low the lasers Sensors.

Learn about limits to resolution. What is fiber optics. Fiber optics is simply strands of flexible glass as thin as human hair that is used for telecommunications. .. These strands carry digital signals with . light.. When hundreds or even thousands of these strands are arranged in bundles, it is called an optical cable.. Raytracing. Lecture 7: Optics.
