Upotreba epitaksijalnih tehnika za realizaciju III-nitridnih naprava sa rezonantnom šupljinom: diode, laseri i polaritonski laseri
dr Zarko Gacevic

In semiconductor microcavities light is confined by high reflectivity distributed Bragg reflectors whereas matter is confined by quantum wells or dots. By proper tuning, the light and matter can be made to interact with one another, forming quasi-particles known as polaritons. The properties of microcavities are exploited for realization of high spectral purity light emitting devices (resonant cavity LEDs and vertical cavity surface emitting lasers) as well as nearly zero-threshold polariton lasers. This talk will be focused on epitaxial fabrication of III-Nitride microcavities for applications in the violet/blue spectral range.
