After completion of this course the student;
- Is familiar with applying quantum mechanics to practical situations in science;
- Has theoretical insight in the main properties of elementary light sources: (a) atoms, (b) molecules, and (c) quantum dots and quantum wells;
- is able to interpret essential optical observations on elementary light sources;
- Is able to select a source that is suited for a particular application.
In this course in the Optics and Biophysics Track, we discuss the optical properties of three main classes of elementary light sources that are used in wide range of optical and biophysical applications. We focus on (a) atoms, (b) molecules, and (c) quantum dots and quantum wells, and analyze their emission in terms of spectra and time-resolved rates. We review the essential quantum mechanics, including static and time-dependent perturbation theory, the variational principle. We also review the complete radiation properties of a classical dipole, including field behavior relevant to near-field effects. |
We discuss in-depth 3 classical and quantum views on spontaneous emission: antennae, circuits, fields, leading to Fermi’s golden rule, selection rules for optical transitions. We investigate the optical properties of an atom, including in an external field. We discuss molecular bonding, and electronic and vibrational transitions in molecules to arrive at fluorescence. After a brief review of the electronic and optical properties of a semiconductor, we study semiconductor quantum wells. We discuss semiconductor quantum dots that are also considered as flexible man-made “artificial atoms”, and that are popular in myriad fields ranging from nanophotonics, lasers, telecom, to photovoltaics and biomedical labeling.
