Optical microresonators are structures which confine light to a small region in the range of one wavelength. A practical design for a single-mode microresonator is formed by two silver mirrors enclosing a transparent dielectric medium with single quantum emitters. The radiation of a quantum emitter is coupled to cavity resonances which leads to an optical confinement of the broadband fluorescence...
FRET plays an important role in light-induced processes in life sciences, e.g. energy transfer in light harvesting complexes. We present a method to tune the energy transfer from donor to acceptor in an optical microresonator.
We present here a tunable microresonator which can be used to modify the optical properties of single quantum emitters. The 3D-orientation and position of a single molecule is determined with a radially polarized laser beam.
We present a general review of different microresonator structures and how they can be used in future device applications in modern analytical methods by tailoring the optical properties of single quantum emitters. The main emphasis is on the tunable λ/2-Fabry–Perot-type microresonator which we used to obtain the results presented in this article. By varying the mirror distance the local mode structure...
