What is Microelectronics
As the name suggests, microelectronics relates to the study and manufacture (or micro fabrication) of very small electronic designs and components. Usually, but not always, this means micrometer-scale or smaller.
1925 Vacuum tubes for almost all complex circuits (switches,amplifiers)
1935 Simple solid-state diodes marketed: made of Se, PBS or Si~
1940 First commercial sources of high-purity Si and Ge. detector diodes used in radar, which was newly-developed concurrent with WWII

Importance of Microelectronics
Microelectronics’ is driving force behind many innovations in other industries.

There are plenty of challenges for any engineering student with an interest in electronic circuits.

Career opportunities are by no means confirmed to a few manufacturers of semiconductor devices.

Microelectronics industry is operating and recruiting on global scale.

Long term perspectives remain intact in an industry that grows in volume and pervasiveness.

Designing a microchip imparts valuable insights in a variety of high – tech areas.

What is Photonics
Photonics
Is the science of light (photon) generation, detection, and manipulation through emission, transmission, modulation, signal processing, switching, amplification, and detection/sensing
What is Photonics
Photonics is derived from the Greek word "photos" meaning light; it appeared in the late 1960s to describe a research field whose goal was to use light to perform functions, that traditionally fell within the typical domain of electronics, such astelecommunications, information processing, etc.
History of Photonics
Photonics as a field began with the invention of the laser in 1960. Other developments followed: the laser diode in the 1970s, optical fibers for transmitting information, 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.

Energy & Communication
With the need for better renewable sources of energy, solar cells have demonstrated their mettle. Newer and newer designs based on engineering allow us to utilize the solar spectrum in the most efficient way and in the process avoiding damage to the cell.
Importance of Photonics
Basic Sciences and Research
Last but not the least, I believe that there is a lot of scope for research and development in optics and photonics. Since the development of the first laser, we have seen so much of technological advancement in this field.
Technologies that uses Photonics

An optical computer (also called a photonic computer) is a device that uses the photons in visible light or infrared ( IR ) beams,rather than electric current, to perform digital computations. An electric current flows at only about 10 percent of the speed of light.
