E&CSE Research Seminar, Wednesday 17th - September - 2008
Speaker: Vajira Amaratunga
Title: Modelling and Numerical Simulation of Semiconductor
Microdisks
Abstract:
Microdisk lasers are tiny devices that
produce very clean laser beams (Single mode). Even though their size is small
(i.e. small mode volume) they can retain energy efficiently with considerably
less losses. Thus they are categorised as high Q resonators. Owing to this high
Q values they enable the creation of ultrasmall devices with extremely low
operational current and low losses which inevitably enhances the continuous wave
performance. The size of Microdisks can be changed to change the lasing colour
(i.e. mode). All these factors make Microdisks a strong contender for next
generation advanced photonic applications.
Even though these devices are very useful
and promising, no detail modelling has been performed yet. In the proposed
research, I intend to accurately model the operation under various conditions
and analyze the performances. The model will include necessary material and
physical parameters to engineer Microdisk lasers.
