Q6. What is photonics and how does it differ from conventional electronics? Examine its applications in communication, healthcare, space and defence. Evaluate India’s preparedness to harness its potential. (15 M)
Difficulty Level: Medium
Reference: TH
Why the question
Photonics is emerging as a foundational technology for AI infrastructure, telecommunications and strategic applications, while India is seeking to develop domestic capabilities under its wider semiconductor ambitions.
Key demand of the question
Define photonics and distinguish it from conventional electronics. Examine its applications in the four specified sectors and evaluate India’s strengths as well as preparedness gaps.
Structure of the answer:
Introduction
Introduce light as an increasingly important medium for transmitting information, sensing physical environments and enabling precision operations in civilian and strategic sectors.
Body
- Photonics and conventional electronics: Clarify the basic principle of photonics and distinguish photons from electrons as information carriers, while noting their complementary role in integrated systems.
- Sectoral applications: Cover the distinctive uses of photonic technologies across communication, healthcare, space and defence through suitable illustrations.
- India’s preparedness: Present a balanced assessment of India’s demand base, scientific capabilities and policy support against weaknesses in manufacturing, finance and the domestic value chain.
Conclusion
Conclude by suggesting that integrating photonics with India’s semiconductor and deep-technology ecosystem can convert its scientific capabilities into technological self-reliance.
