Laser cooling of a nanomechanical oscillator into its quantum ground state
The simple mechanical oscillator, canonically consisting of a coupled mass–spring system, is used in a wide variety of sensitive measurements, including the detection of weak forces and small masses.… Expand
Electromagnetically induced transparency and slow light with optomechanics
We demonstrate tunable optical delay of 50 nanoseconds with near-unity optical transparency, and superluminal light with a 1.4 microsecond signal advance using photon–phonon interactions. Expand

Controlling the interaction between localized optical and mechanical excitations is now possible following advances in micro- and nano-fabrication techniques. To date, most experimental studies of… Expand
Polarization-selective excitation of nitrogen vacancy centers in diamond
The nitrogen vacancy (NV) center in diamond is promising as an electron spin qubit due to its long-lived coherence and optical addressability. The ground state is a spin triplet with two levels… Expand

In this Letter we use resolved sideband laser cooling to cool a mesoscopic mechanical resonator to near its quantum ground state (phonon occupancy 2.6±0.2), and observe the motional sidebands… Expand
Optomechanics in an ultrahigh-Q two-dimensional photonic crystal cavity
We demonstrate an ultrahigh-Q slotted two-dimensional photonic crystal cavity capable of obtaining strong interaction between the internal light field and the mechanical motion of the slotted… Expand

A fully planar two-dimensional optomechanical crystal formed in a silicon microchip is used to create a structure devoid of phonons in the GHz frequency range. A nanoscale photonic crystal cavity is… Expand
Electrostatically tunable optomechanical "zipper" cavity laser
A tunable nanoscale “zipper” laser cavity, formed from two doubly clamped photonic crystal nanobeams, is demonstrated. Pulsed, room temperature, optically pumped lasing action at λ = 1.3 μm is… Expand
Surface-plasmon mode hybridization in subwavelength microdisk lasers
Hybridization of surface-plasmon and dielectric waveguide whispering-gallery modes are demonstrated in a semiconductor microdisk laser cavity of subwavelength proportions. A metal layer is deposited… Expand
Optomechanical zipper cavity lasers: theoretical analysis of tuning range and stability.
The design of highly wavelength tunable semiconductor laser structures is presented. The system is based on a one dimensional photonic crystal cavity consisting of two patterned, doubly-clamped… Expand
