Photonics - My Favourite
Subject |
Photonics
is the science of generating, controlling, and detecting
photons. I have done my |
post graduation in
this field, more specifically; Opto-Electronics & Laser Technology. |
|
|
Photons are
discrete parcels of energy, which have dual nature – that of a particle and
a wave. |
Photonics
as a field really began in 1960, with the invention of the laser,
|
and the laser
diode followed in the 1970s by the development of optical fibers |
as a medium for
transmitting information using light beams, |
and the
Erbium-doped fiber amplifier. These inventions formed the basis for
the |
telecommunications
revolution of the late 20th century, and |
provided the
infrastructure for the internet. |
Photonics
covers a huge range of science and technology
applications, including: |
laser
manufacturing,
biological and
chemical sensing,
medical
diagnostics and therapy,
display
technology,
optical
computing. |
|
Again, a category wise application list of Photonics can be given as
follows:- |
|
Consumer Equipment: Barcode scanner, printer, CD-ROM, VCD, CD player,
remote control devices |
|
Telecommunications: Optical fiber communications |
|
Medicine: correction of poor eyesight, removal of port wine stains,
laser surgery, surgical endoscopy, tattoo removal |
|
Industry: laser welding, laser cutting, laser etching |
|
Construction: laser levelling, laser range finding, smart structures |
|
Military: IR sensors, Command and Control, Search and Rescue, Mine
Laying and Detection |
|
Entertainment: Lasershow, beam effects, holographic art , |
