Tunable resonant optical microcavities by self-assembled templating

By G. Vijaya Prakash, L. Besombes, T. Kelf, Jeremy J. Baumberg, P.N. Bartlett and M.E. Abdelsalam


Micrometer-scale optical cavities are produced by a combination of template sphere self-assembly and electrochemical growth. Transmission measurements of the tunable microcavities show sharp resonant modes with Q factors of >300 and 25-fold local enhancement of light intensity. The presence of transverse optical modes confirms the lateral confinement of photons. Calculations show that submicrometer mode volumes are feasible. The small mode volumes of these microcavities promise to lead to a wide range of applications in microlasers, atom optics, quantum information, biophotonics, and single-molecule detection
