Measurement of optical forces within a high-Q microcavity-waveguide system

Quantum Electronics and Laser Science Conference (2007)

Matt Eichenfield Oskar Painter

Optical forces arising from the intense stored field within a high-Q microdisk cavity are measured through the displacement of a moveable, micron-scale fiber taper input waveguide. Tunable waveguide-cavity coupling is demonstrated at sub-mW input powers.

Enhanced Quantum Nonlinearities in a Two-Mode Optomechanical System

Physical Review Letters (2012)

Max Ludwig Amir H. Safavi-Naeini Oskar Painter Florian Marquardt

In cavity optomechanics, nanomechanical motion couples to a localized optical mode. The regime of single-photon strong coupling is reached when the optical shift induced by a single phonon becomes comparable to the cavity linewidth. We consider a setup in this regime comprising two optical modes and one mechanical mode. For mechanical frequencies nearly resonant to the optical level splitting, we find the photon-phonon and the photon-photon interactions to be significantly enhanced. In addition to dispersive phonon detection in a novel regime, this offers the prospect of optomechanical photon measurement. We study these quantum nondemolition detection processes using both analytical and numerical approaches.

Collapse and Revival of an Artificial Atom Coupled to a Structured Photonic Reservoir

arXiv (Cornell University) (2020)

Vinicius S. Ferreira Jash Banker Alp Sipahigil Matthew H. Matheny Andrew J. Keller

A structured electromagnetic reservoir can result in novel dynamics of quantum emitters. In particular, the reservoir can be tailored to have a memory of past interactions with emitters, in contrast to memory-less Markovian dynamics of typical open systems. In this Article, we investigate the non-Markovian dynamics of a superconducting qubit strongly coupled to a superconducting slow-light waveguide reservoir. Tuning the qubit into the spectral vicinity of the passband of this waveguide, we find non-exponential energy relaxation as well as substantial changes to the qubit emission rate. Further, upon addition of a reflective boundary to one end of the waveguide, we observe revivals in the qubit population on a timescale 30 times longer than the inverse of the qubit's emission rate, corresponding to the round-trip travel time of an emitted photon. By tuning of the qubit-waveguide interaction strength, we probe a crossover between Markovian and non-Markovian qubit emission dynamics. These attributes allow for future studies of multi-qubit circuits coupled to structured reservoirs, in addition to constituting the necessary resources for generation of multiphoton highly entangled states.

Feasibility of detecting single atoms using photonic bandgap cavities

Nanotechnology (2004)

Benjamin Lev Kartik Srinivasan Paul E. Barclay Oskar Painter Hideo Mabuchi

We propose an atom-cavity chip that combines laser cooling and trapping of neutral atoms with magnetic microtraps and waveguides to deliver a cold atom to the mode of a fiber taper coupled photonic bandgap (PBG) cavity. The feasibility of this device for detecting single atoms is analyzed using both a semi-classical treatment and an unconditional master equation approach. Single-atom detection seems achievable in an initial experiment involving the non-deterministic delivery of weakly trapped atoms into the mode of the PBG cavity.

Wannier-like equation for the resonant cavity modes of locally perturbed photonic crystals

Physical review. B, Condensed matter (2003)

Oskar Painter Kartik Srinivasan Paul E. Barclay

In analogy to the Wannier equation for localized electronic impurity states in crystalline materials, a wave equation for the envelope of the resonant optical modes of local defects within two-dimensional periodic dielectric structures is derived. In the case of degenerate satellite extrema, this is generalized to a set of coupled Wannier-like equations for a multienvelope system. The localized Wannier envelope solutions are then used in conjunction with a group theoretical symmetry analysis to determine an approximate form for donor and acceptor modes in a hexagonal photonic crystal. For an effective harmonic potential formed by varying the filling fraction of the lattice, the localized resonant modes are explicitly calculated using the Wannier equation and symmetry analysis, and a comparison to exact numerically computed modes is presented.

Multispectral Quantum Dots-in-a-Well Infrared Detectors Using Plasmon Assisted Cavities

IEEE Journal of Quantum Electronics (2010)

R. V. Shenoi Jessie Rosenberg Thomas E. Vandervelde Oskar Painter Sanjay Krishna

We present the design, fabrication, and characterization, of multi-spectral quantum dots-in-a-well (DWELL) infrared detectors, by the integration of a surface plasmon assisted resonant cavity with the infrared detector. A square lattice and rectangular lattice cavity, formed by modifying the square lattice have been used in this design. By confining the resonant mode of the cavity to detector active region, the detector responsivity and detectivity have been improved by a factor of 5. A spectral tuning of 5.5 to 7.2 ¿m has been observed in the peak response of the detectors, by tuning the lattice constant of the cavity. Simulations indicate the presence of two modes of absorption, which have been experimentally verified. The use of a rectangular lattice predicts highly polarization sensitive modes in x - and y -direction, which are observed in fabricated detectors. A peak detectivity of 3.1 x 10 ⁹ cm·¿{Hz} /W was measured at 77 K. This design offers a cost-effective and simple method of encoding spectral and polarization information, in infrared focal plane arrays.

Ultra-high-Q wedge-resonator on a silicon chip

arXiv (Cornell University) (2011)

Hansuek Lee Tong Chen Jiang Li Ki Youl Yang Seokmin Jeon

Ultra-high-Q optical resonators are being studied across a wide range of research subjects including quantum information, nonlinear optics, cavity optomechanics, and telecommunications. Here, we demonstrate a new, resonator on-a-chip with a record Q factor of 875 million, surpassing even microtoroids. Significantly, these devices avoid a highly specialized processing step that has made it difficult to integrate microtoroids with other photonic devices and to also precisely control their size. Thus, these devices not only set a new benchmark for Q factor on a chip, but also provide, for the first time, full compatibility of this important device class with conventional semiconductor processing. This feature will greatly expand the possible kinds of system on a chip functions enabled by ultra-high-Q devices.

Thermalization properties at mK temperatures of a nanoscale optomechanical resonator with acoustic-bandgap shield

arXiv (Cornell University) (2014)

Seán M. Meenehan Justin Cohen Simon Groeblacher Jeff T. Hill Amir H. Safavi-Naeini

Optical measurements of a nanoscale silicon optomechanical crystal cavity with a mechanical resonance frequency of 3.6GHz are performed at sub-kelvin temperatures. We infer optical-absorption-induced heating and damping of the mechanical resonator from measurements of phonon occupancy and motional sideband asymmetry. At the lowest probe power and lowest fridge temperature (10mK), the localized mechanical resonance is found to couple at a rate of 400Hz (Q=9x10^6) to a thermal bath of temperature 270mK. These measurements indicate that silicon optomechanical crystals cooled to millikelvin temperatures should be suitable for a variety of experiments involving coherent coupling between photons and phonons at the single quanta level.
