Mode Behavior of Coupled Photonic Cavities — •Dennis Ehmer, Matthias Reichelt, and Torsten Meier — Department Physik, Universität Paderborn, Warburger Str. 100, D-33098 Paderborn, Germany
The mode behavior of several coupled photonic cavities embedded in a
dielectric Bragg structure is investigated numerically using the
finite-difference time-domain algorithm . It is shown that for the case of three cavities
the well-known symmetry of the eigenmodes leads to a zero field in one
of the cavities which has also been recently measured for three
coupled microdisk resonators . Furthermore, the coupling strength
between two cavities depending on geometrical parameters is
determined.  It is planned to additionally introduce semiconductor
quantum dots into the cavities.
