1. All-angle negative refraction and active flat lensing of ultraviolet light
Topic: Optics
Published: 5/22/2013
Authors: Ting Xu, Amit Kumar Agrawal, Maxim Abashin, Kenneth John Chau, Henri J Lezec
Abstract: The ability of a left-handed medium to sustain backwards electromagnetic waves leads to counter-intuitive phenomena such as negative refraction. We report the experimental implementation of a three-dimensional negative-index metamaterial operating at ...

2. Revisiting the Balazs thought experiment in the case of a left-handed material: electromagnetic-pulse-induced displacement of a dispersive, dissipative negative-index slab
Topic: Optics
Published: 3/23/2013
Authors: Henri J Lezec, Kenneth John Chau
Abstract: We propose a set of postulates to describe the mechanical interaction between a plane-wave elec- tromagnetic pulse and a dispersive, dissipative slab having a refractive index of arbitrary sign. The postulates include the Abraham electromagnetic mom ...

3. Experimental demonstration of a receiver beating the standard quantum limit for multiple nonorthogonal coherent-state discrimination
Topic: Optics
Published: 1/6/2013
Authors: Francisco Elohim Becerra Chavez, Jingyun Fan, Gerald Baumgartner, Julius Goldhar, Jonathan Kosloski, Alan L Migdall
Abstract: The measurement of the state of a quantum system with inherent quantum uncertainty (noise) approaching the ultimate physical limits is of both technological and fundamental interest. Quantum noise prevents any mutually nonorthogonal quantum states ...

4. Slot-mode-coupled optomechanical crystals
Topic: Optics
Published: 10/22/2012
Authors: Marcelo Ishihara Davanco, Jasper Chan, Amir H. Safavi-Naeini, Oskar Painter, Kartik A Srinivasan
Abstract: We design a cavity optomechanical system in which a localized GHz frequency mechanical mode of a nanobeam resonator is evanescently coupled to a high quality factor (Q > 10^6) optical mode of a separate nanobeam optical cavity. Using separate nanobea ...

5. Probing coherence in microcavity frequency combs via optical pulse shaping
Topic: Optics
Published: 8/29/2012
Authors: Fahmida Ferdous, Houxun H. Miao, Pei-Hsun Wang, Daniel E. Leaird, Kartik A Srinivasan, Lei Chen, Vladimir A Aksyuk, Andrew M Weiner
Abstract: Recent investigations of microcavity frequency combs based on cascaded four-wave mixing have revealed a link between the evolution of the optical spectrum and the observed temporal coherence. Here we study a silicon nitride microresonator for which ...

6. A compact and robust method for full Stokes spectropolarimetry
Topic: Optics
Published: 8/1/2012
Authors: William Sparks, Thomas Avery Germer, John MacKenty, Frans Snik
Abstract: We present an approach to spectropolarimetry which requires neither moving parts nor time dependent modulation, and which oers the prospect of achieving high sensitivity. The concept, which is one of those generically known as channeled polarimetry, ...

7. Optimal Laser Scan Path for Localizing a Fluorescent Particle in Two or Three Dimensions
Topic: Optics
Published: 7/16/2012
Authors: Gregg M. Gallatin, Andrew J. Berglund
Abstract: Localizing a fluorescent particle by scanning a focused laser in its vicinity and analyzing the detected photon stream provides real-time information for a modern class of feedback control systems for particle tracking and trapping. We present a sim ...

8. Demonstration of Superluminal Images
Topic: Optics
Published: 6/19/2012
Authors: Ryan Thomas Glasser, Ulrich Vogl, Paul D Lett
Abstract: Optical pulse propagation with group velocities larger than the speed of light in vacuum, c, or negative, have been demonstrated theoretically and experimentally in a variety of systems [1–5]. The anomalous dispersion required for generating “fast” l ...

9. Stimulated Generation of Superluminal Light Pulses via Four-wave Mixing
Topic: Optics
Published: 4/26/2012
Authors: Ryan Thomas Glasser, Ulrich Vogl, Paul D Lett
Abstract: We report on the four-wave mixing of superluminal pulses, in which both the injected and generated pulses involved in the process propagate with negative group velocities. Generated pulses with negative group velocities of up to vg = −c/880 ar ...

10. Phase sensitive parametric optical metrology: Exploring the limits of 3-dimensional optical metrology
Topic: Optics
Published: 4/4/2012
Authors: Richard M Silver, Jing Qin, Bryan M Barnes, Hui Zhou, Ronald G Dixson, Francois Romain Francis Goasmat
Abstract: There has been much recent work in developing advanced optical metrology applications that use imaging optics for critical dimension measurements, defect detection and for potential use with in-die metrology applications. Sensitivity to nanometer sca ...
