Photonics Integrated Circuit Design (PIC)

Light is the source of life on earth. It has been the guiding force for the human species since they evolved on surface of earth. Humans have been trying to harness light energy for improving their living environment for over thousands of years. It’s the ability of the humans to visually see things which has inspired their imagination to create technology by understanding working of things from nature.

In last two centuries with advent of modernity and technological breakthroughs light has become integral part of day to day life. Today, transmission of visual images is common phenomena. Light engulfs every technological aspects of life from medicine, photography, guidance systems, navigation systems, industrial manufacturing etc. Generating light, transmitting light and manipulating light properties for various applications has contributed to development of many technologies like fiber optic communication systems, laser based engineering systems, optics, light based diagnostics & therapeutic systems, sensor systems etc.

Technological limitations posed by electronics based devices in-terms of miniaturization in further reducing dimensional aspects of devices and systems, have led to considering optical integrated circuits in recent decades. Similar to Very Large Scale Integrated Circuits (VLSI) using electron as medium for transmissions of signal, Photon as a signal carrier in integrated circuit using basic optical devices has evolved as Photonics Integrated Circuits (PIC).

PIC based Integrated Circuits have many advantages compared to electronics based circuit design. This is an emerging technology in tandem with electronics. Photonics requires professionals from physics, semiconductor technology, microfabrication and Computer Aided Tools for PIC design. PPCRC research is focused on development PIC designs for different applications.
