Designing of Antireflection Coating for Optical DEvices


  • No


Course will describe details of interference phenomena in real life. It is extended in the direction that how interference concepts are applied in day today life applications.

Interference is redistribution of intensity of light. Redistribution of light intensity occurs due to various aspects like superposition of two or more waves simultaneously. It results in various magical images that we observe as scenery. Apart from natural features of picturesque images, an interference phenomenon has multiple scientific and technical applications.

Keeping in view these application this course initially tries to correlate real life situations and how natures mimicry can be utilized for betterment of human life. Course includes types of interference, conditions for obtaining steady interference pattern, thin film interference, types of thin films which provide steady interference pattern, conditions for interference in uniform thickness and wedge shape thin films and their applications as surface flatness testing and antireflection coatings.

Antireflection coating is often used as top layer of optical devices like camera lens, spectacles, telescope lens, and window glass pane. It is also used for light related electrical device like solar cell. Antireflection coating works against reflection of incident light and it allows transmitting maximum light. Due to this images obtained with optical devices are sharp and clear.

Since, last 10 years of my research career I am working on Electrochemical Photovoltaic (ECPV) solar cell electrode materials such as metal chalcogenides with the exploitation of chemical methods for cost effectiveness. Simultaneously, I am working on theoretical modeling of degradation of these materials and standard silicon and GaAs solar cells under space environment.

Keeping in mind numerous advantages of electrodeposition technique and of nanocrystalline ZnS, InSe, ZnSe, ZnIn2Se4, CdSe, CdIn2Se4 thin film materials, these thin films were electrodeposited by potentiostatic technique .

As a part of optoelectronics Instructor has keen interest in Interference and its space and technical applications.
