Laser and Its applications
Objective: The main aim of this course is to equip students with the understanding of the fundamental of laser, their usage, and their application in a real scenario. The objective of this course is not only to teach but also to develop the student’s capacity to analyze the contents of topics, idea generation for solving problems, and develop the habits of writing research papers.
During this course, students should research the different fields of photonics, which are of their interest. Upon completion of the course, students should be able to analyze the photonics system and present the research work based on laser devices for the applications they are interested in.

Chapter objectives:
Chapter 1: Basic of Photonics
This chapter provides a basic understanding of photonics, how it is different from electronics (the advantages of Photonics and challenges), and present their implementation for real application scenario. With the completion of this chapter, students will be able to grasp the fundamental of optics, possibilities, and their contribution to shaping future technology.
Chapter 2: Light Sources and Basic Components of Lasers
This chapter discusses different types of light sources, natural and artificial, and their characteristics and differences. Putting more focus on the basic components of lasers, it clarifies the fundamental differences with LED.
Chapter 3: PN Junctions Semiconductors and Amplifiers Principle:
In this chapter, we will focus on semiconductor materials and how amplification functions. We analyze the metal, insulators, and semiconductors basics and discuss some of the semiconductors used for the light sources.
Chapter 4: Types of Lasers and Output Characteristics:
This chapter focuses on the detailed analysis of the laser diodes and types of Laser diodes, multimode lasers, different types of single mode lasers, output characteristics, and their usage in the optical domain. This type of laser diode includes Multimode and single mode lasers such as FP-LD, ECFP-LD, DFB, DBR, VCSELS, Quantum Dot lasers, and more.
Chapter 5: Practical Handling of Laser Diodes
In this section, we focus on different parameters that should be considered while using the laser diode in real application, requirements, and safety to be considered while working with the laser diodes.
Chapter 6: FPLD and DFB lasers and Operating Principles:
We mainly focus on FPLD and DFB lasers in this section focusing on the basic operating principles of laser diodes for use in real applications. The main principle we will be discussing is the P1 oscillations, injection locking, hysteresis width, and their usage.
Chapter 7: Lasers and Applications:
In this section, we mainly focus on the laser’s application in Digital photonics, Microwave Photonics, waveform generation for photonics-based radar, and interference mitigation techniques.
