Abstract

We used scanning confocal microscopy to study the fluorescence from a single terrylene molecule embedded in a thin polymer film of polymethyl methacrylate, at room temperature, with a high signal-to-background ratio. The photon-pair correlation function g2τ exhibits perfect photon antibunching at τ=0 and a limit of 1.3, compatible with bunching associated with the molecular triplet state. Application of this molecular system to a triggered single-photon source based on single-molecule fluorescence is investigated.

At room temperature, the coherence terms in the optical Bloch equations vanish and these equations reduce to rate equations that can be solved analytically see, for example, B. de Bartolo, Optical Interactions in Solids (Wiley, New York, 1968).

Hanbury-Brown–Twiss-type setup for g2 measurement with our scanning confocal microscope. PZT, xyz piezoelectric translation stage (PiezoJena); SMF; single-mode fiber; DM, dichroic mirror; O, microscope objective (Nikon, 60×; N.A., 1.4); PH, pinhole ϕ=30 μm; NF, holographic notch filter; BS, nonpolarizing beam splitter; Fs, short-pass glass filters (3-mm-thick Schott KG 4); APDs, single-photon-counting avalanche photodiodes (EG&G SPCM-AQR15); TAC, time–amplitude converter; MCA, multichannel analyzer. The FWHM lateral resolution of the confocal microscope is 320  nm. Inset, three-level model of the molecular response.
