چکیده
We theoretically demonstrate high Quality factor (Q~3×10 6 ) micropillar cavities with record low mode volumes [V~0.1(λ/n) 3 ] based on the TiO2/SiO2 material system. The proposed cavities have Q/V three orders of magnitude larger than previously reported ones. We show that our cavity embedded with diamond nanocrystal provides a feasible platform for cavity quantum electrodynamics experiments in the strong coupling limit. 2008 Optical Society of America

Submicrometer diameter micropillar cavities with high quality factor and ultrasmall mode volume.
We theoretically demonstrate high quality factor (Q approximately 3x10(6)) micropillar cavities with a record low mode volume [V approximately 0.1(lambda/n)3] based on the TiO2/SiO2 material system. The proposed cavities have Q/V that is 3 orders of magnitude larger than previously reported ones. We show that our cavity embedded with a diamond nanocrystal provides a feasible platform for cavity...
متن کاملOptical fiber coupling to planar photonic crystal microcavities
Recently it has been demonstrated that resonant microcavities formed in planar photonic crystals (PC) are capable of not only confining light to ultra-small optical mode volumes[1], but can also be made of high enough quality to enable photon cavity lifetimes capable of, for instance, reaching strong-coupling with atomic Cs[2] or semiconductor quantum dots[1, 3, 4]. In many of the proposed appl...
متن کاملProposal and numerical study of ultra-compact active hybrid plasmonic resonator for sub-wavelength lasing applications
We design an ultra-compact active hybrid plasmonic ring resonator for lasing applications at deep sub-wavelength scale. The combined contributions of hybrid plasmonic mode, circular-shaped cross section of nanowire, and ring resonator structure with round-trip whispering-gallery cavity, benefit reduced metallic absorption loss, tight mode confinement, enhanced cavity feedback, achieving high qu...
متن کاملOptical properties of red emitting self-assembled InP/(Al0.20Ga0.80)0.51In0.49P quantum dot based micropillars.
Using focused ion beam etching techniques, micropillar cavities were fabricated from a high reflective AlAs/AlGaAs distributed Bragg reflector planar cavity containing self-assembled InP quantum dots in (Al(0.20)Ga(0.80))(0.51)In(0.49)P barrier layers. The mode spectra of pillars with different diameters were investigated using micro-photoluminescence, showing excellent agreement with theory. Q...
متن کاملHigh quality two-dimensional photonic crystal slab cavities
We have fabricated and characterized donor-mode nanocavities formed by a single defect cavity defined within a two-dimensional photonic crystal slab. Quantum dots emitting in the 1.1–1.3 micron range were used as luminescence sources, and a design using fractional edge dislocations was used to demonstrate well-confined dipole modes with high quality factors. By applying the fractional dislocati...
