Photonic materials for Laser, Biomedical & Sensor Applications
Course Coordinator: Dr. Sunil Verma & Dr. Pankaj Misra, RRCAT
Course Summary: The objective of this course is to provide comprehensive knowledge of photonic materials including bulk crystals, nanostructured metal oxide thin films and polymers composites, fabrication of device structures and their characterizations for laser, biomedical and sensor applications. The course is intended for the masters and graduate students, and early career faculties working in the related fields and will consist of about 12 lectures. The course will begin with discussions on fundamental properties of nonlinear optical materials, laser host and detector/sensor materials in the form of single crystal, nanostructured thin films and polymer composite for aforementioned applications. Modern growth methodologies used for fabrication of bulk and nanostructured photonic materials for laser, biomedical and sensor applications will be discussed in details. Fundamentals of pulsed laser and atomic layer deposition techniques for growth of nanostructured thin films of metal oxides and pertinent growth mechanisms will be discussed. This will be followed by discussion on fundamentals and working principle of relevant material characterization techniques pertinent to aforesaid applications. Emphasis will be given on laser based techniques for real-time and in-situ crystal growth kinetic and photoluminescence lifetime studies etc. Post growth processing of grown material and fabrication of prototype device elements using photolithography and interdigital electrodes for particular applications will discussed. The last part of course will deal with characterizations and measurement protocols of device structures based on photonic materials for above mentioned applications.
