Video Lecture Series from IIT Professors :
Optoelectronic Materials and Devices by Prof. D.N.Bose sir

Prof. D.N. Bose

He is presently Scientific Adviser, Advanced Technology Center. He was formerly Professor, Materials Science Center, I.I.T Kharagpur from 1977 - 1985 and again in 1987 - 1997. He has also held teaching assignments at the E.C.E Dept., I.I.Sc Bangalore from (1970 - 1977); and at Virginia Tech U.S.A, (1985-86). He received his Ph.D. in Physics from University of Reading, U.K. in 1965. His Research Areas include: Bulk crystal growth, Epitaxy and PECVD; Surfaces & Interfaces; Solid state Ionics & Ferroelectrics; Optoelectronics, Lasers & Photodetectors. He was the recipient of the Ramlal Wadhwa Gold Medal of I.E.T.E 1984, and Fellow, Indian Academy of Sciences 1989. 

Course outline :The course deals with the following topics : Optical properties of semiconductors, MOVPE & MBE, strained layers, critical thickness, band-structure, photoconductivity - gain & bandwidth of photodetectors, p-n junction & p-i-n photodiodes, APDs, resonant cavity & quantum well photodetectors. Luminescence - Configuration coordinate diagram, LEDS-quantum efficiency and frequency response; Spontaneous & stimulated Emission, principle of SC laser- threshold current density & confinement factor, p-n homo, SH & DHJ lasers; DFB & DBR lasers; low dimensional effects - Quantum well lasers - advantages & performance. F-K & Stark effects; optical modulators- electro-optic & SEED, OEICs. Applications in Fibre-Optics, Remote sensing, IR Detection & Imaging.
