optics fiber optics and Snell's Law, Internal Reflection. Occurs when light is going from
higher to lower index at large angles. Uses Snell's Law |
Fish-eye view
When light propagates from one medium into another, its speed changes, which
causes the light to reflect and refract at the boundary |
Grating
reflectance The reflectance as a function of wavelength is computed for an
index modulation Bragg grating |
Graded Index Fiber
The graded-index(GRIN)fiber has a core material whose reflective index varies
with distance from the fiber axis, Graded Index Fiber |

Interference between light waves
Interference between light waves is the
reason that thin films, such as soap bubbles, show colorful patterns. This is
known as thin-film interference - interference between light waves reflecting
off the top surface of a film with waves reflecting from the bottom surface |

Laser cavity
An optical cavity or optical resonator is an arrangement of mirrors that forms a
standing wave cavity resonator for light waves. Optical cavities are a major
component of lasers, surrounding the gain medium and providing feedback of the
laser light, laser cavity animation |

the Best Light for Optical Fiber Communications Laser light is used for
optical fiber communications for the simple reason that it is a single
wavelength light source |
Laser: Mechanism
of a Free Electron Laser Free electron lasers make use of the phenomenon in
which electrons traveling straight near the speed of light will release light if
their course takes a sudden turn. If you place magnets with their north and
south poles facing each other, and then fire in an electron at high speed |

Refraction of
light you can download the applet, the incident angle can be varied from 0
to 85 degrees, the index of refraction of the second medium can be varied from
n=1.00 (for vaccuum) to a maximum of n=2.42 (diamond) |
Sending
Light by Optical Fiber Optical fibers have cores with diameters ranging from
10 to 50 microns. Optical signals are fed into the cores of these fibers using
devices known as LD (laser diode) modules. Laser light generated by a
high-output laser diode is passed through the lenses of the LD module to be fed
into the fiber core |
Single
Mode and Multimode Optical fibers can be divided broadly into two types
according to the way in which they transmit optical signals. One type, known as
single-mode fiber, has a thin core with a diameter of about 10 microns, and
allows light pulses to propagate in only one mode. The other type, multimode
fiber, has a thick core of about 50 microns in diameter, and permits the
propagation of multiple light pulses of differing angles of reflection |

Snell's Law: n1 < n2
This simulation can help you see what happens to a light beam when it goes from
one medium into another. The light beam is refracted according to Snell's

Trapping
Light in a Core Optical fibers are composed of a central core, and a
surrounding layer known as the cladding. The core is provided with a high
refractive index, while a lower refractive index is used for the cladding. This
difference in refractive indices is incorporated to ensure smooth travel of
light along the core |
