Hybrid quantum information protocols are based on local qubits, such as trapped atoms, NV centers, and quantum dots, coupled to photons. The coupling is achieved through optical cavities. Here we demonstrate far-field optimized H1 photonic crystal membrane cavities combined with an additional back reflection mirror below the membrane that meet the optical requirements for implementing hybrid quantum information protocols. Using numerical optimization we find that 80% of the light can be radiated within an objective numerical aperture of 0.8, and the coupling to a single-mode fiber can be as high as 92%. We experimentally prove the unique external mode matching properties by resonant reflection spectroscopy with a cavity mode visibility above 50%.read more

TL;DR: A genetic algorithm is used to find a global maximum of the quality factor of defect-cavities in photonic crystal slabs, by varying the positions of few neighbouring holes, and consistently finds Q-values above one million – one order of magnitude higher than previous designs.

High- Q photonic nanocavity in a two-dimensional photonic crystal
TL;DR: A silicon-based two-dimensional photonic-crystal slab is used to fabricate a nanocavity with Q = 45,000 and V = 7.0 × 10-14 cm3; the value of Q/V is 10–100 times larger than in previous studies, underlying the realization that light should be confined gently in order to be confined strongly.

Optical microcavities : Photonic technologies
TL;DR: Optical microcavities confine light to small volumes by resonant recirculation as discussed by the authors, and are indispensable for a wide range of applications and studies, such as long-distance transmission of data over optical fibres; they also ensure narrow spot-size laser read/write beams in CD and DVD players.

Temporal coupled-mode theory for the Fano resonance in optical resonators
TL;DR: A theory of the Fano resonance for optical resonators, based on a temporal coupled-mode formalism, is presented and it is shown that the coupling constants in such a theory are strongly constrained by energy-conservation and time-reversal symmetry considerations.
