In order to control light, different strategies have been applied by placing an optically active medium into a semiconductor resonator and certain applications such as LEDs and laser diodes have been commercialized for many years. The possibility of nanoscale optical applications has created great interesting for quantum nanostructure research. Recently, single photon emission has been an active area of quantum dot research. A quantum dot is place between distributed Bragg reflectors (DBRs) within a micro-pillar structure. In this study, we shall report on an active layer composed of an organic material instead of a semiconductor. The micro-pillar structure is fabricated by a focused ion beam (FIB) micro-machining technique. The ultimate target is to achieve a single molecule within the micro-pillar and therefore to enable single photon emission. Here, we demonstrate some results of the fabrication procedure of a 5 micron organic micro-pillar via the focused ion beam and some measurement results from this study. The JEOL 6500 dual column system equipped with both electron and ion beams enables us to observe the fabrication procedure during the milling process. Furthermore, the strategy of the FIB micro-machining method is reported as well.

A novel dendrimer containing eight perylene diimide chromophores has been synthesized and studied by ensemble and single-molecule spectroscopic techniques. Photon anti-bunching (coincidence) measurements on single molecules embedded in zeonex polymer films show that the dendrimer behaves as a deterministic (triggered) single photon source with only one fluorescence photon being emitted following pulsed laser excitation, even when more than one chromophore is excited. This behaviour is due to efficient singlet–singlet annihilation being operative in this dendrimer. Preliminary results indicate that the triplet lifetime and yield for this molecule are similar to the values for a molecule containing a single perylene diimide chromophore.
