What is Photonics??
¾ Photonics is about interaction of light with matters.
¾ Light is everywhere – first thing greets you.
¾ Photonics deals with generation, amplification, guiding,
modulation, detection of light.
Photonic applications
Energy, security, biotechnologies, low-cost precision manufacturing,
internet, information processing, manufacturing, and many others!
Laser cutting, marking
Optical communication
Defense
Display & 3D display
Bioimaging, laser surgery
Green technology
Thematic DIP on Photonics
¾ Industry sponsored projects, to learn real-world
industry process for product development
¾ You can also propose your own interested
projects
¾ Solve real-world problems and learn how to work
collaboratively to solve challenging tasks.
¾ Can be continued for IA or FYP

Example 2: Solar Car by Wireless Power Transfer
Objective: the main objective of this project is to power up an electric vehicle by using solar energy and wireless inductive energy transfer without cords
A solar-powered electric
vehicle charging station
in Rio de Janeiro, Brazil
Scope: •Solar cell circuit
Produce more than 12V to be able to charge the lead acid battery.
•Infrared sensor circuit
Turn on the supply to the sending‐end of the inductor coil to commence charging of the car’s battery
•Wireless inductive charging circuit
Sending‐end of the inductor coil (connected to the lead acid battery)
Receiving‐end of the inductor coil (connected to car)
•Wireless inductive charging station
Integration of the solar panel circuit, infrared sensor circuit, wireless inductive charging circuit and lead acid battery
