Today's Colloquium. 3:30 p.m. Meinel 307
Henry Lezec of NIST will present Negative Radiation Pressure. Masud Mansuripur is the host.
Abstract: Four decades ago, V. Veselago derived the electromagnetic properties of a hypothetical material having simultaneously-negative values of electric permittivity and magnetic permeability [1]. Such a “left-handed” material was predicted to exhibit a number of exotic properties including a negative index of refraction and a negative response to radiation pressure (pull). Since left-handed materials are not available in nature, considerable efforts are currently under way to implement them under the form of artificial “metamaterials” – composite media with tailored bulk optical characteristics resulting from constituent structures which are smaller than the effective wavelength in the medium.
Here we show how surface-plasmon modes propagating in a stacked array of metal-insulator-metal (MIM) waveguides can be harnessed to yield a volumetric left-handed metamaterial characterized by an in-plane-isotropic index of refraction which is negative over a broad portion of the visible-frequency range. By sculpting this metamaterial with a focused-ion beam, we realize micro-cantilevers which we use to demonstrate, for the first time, a negative radiation pressure. We also predict and experimentally verify a negative “super-pressure” of magnitude significantly greater than the largest photon pressure achievable under normal circumstances – that experienced by a perfect mirror.

Friday's OSC Community Speakers. Noon. Meinel 410
From Boris Glebov, Tim Renkoski, and Garam Yun. Please join us for our 6th Community Speaker Series and free pizza. This week features presentations by Justin Paul and Anna-Britt Mahler.
Justin will present Lasers, Lasers Everywhere, But Not a Drop (Hg) to Drink...Yet. Abstract: He will give a brief motivation behind laser-cooling of mercury atoms, and the new exciting physics that can be accessed in the process. Also he will describe the laser engineering we have been doing to create all of our own, home-built laser sources. He will explain briefly the connection between the two Jones labs: ultrafast optics and precision spectroscopy. This strange "marriage" between two seemingly unrelated disciplines has been made possible with the development of the femtosecond frequency comb. Extending this comb from IR and visible light into the vacuum ultraviolet regime could yield a new coherent laser source to perform spectroscopy, materials science and fundamental physics in a range previously inaccessible to lasers.
Anna-Britt will present Multiangle SpectroPolarimetric Imager (MSPI). The Multiangle SpectroPolarimetric Imager (MSPI) is a candidate instrument for the Aerosol-Cloud-Ecosystem (ACE) mission. MSPI is a multiangle, multispectral, high-accuracy polarization imager, and is envisioned to contain multiple cameras pointed at different view angles, having wavebands from the UV into the SWIR, and accurate polarimetric imaging in a subset of the bands. To achieve a degree of linear polarization (DOLP) uncertainty of 1%, we temporally modulate the linear polarization component of the incident Stokes vector, which allows each detector having an analyzer to measure relative proportions of Q, U, and total irradiance, I. Our system uses tandem photoelectric modulators (PEMs) within a reflective design. She will report on a sample of interesting aspects of this project, including the achromatic quarter wave retarders, the mirror coatings, and the polarization calibration instrumentation (the partial polarization state generator).
Undergraduates, Community speaker series are not only for graduate students. So please join us! As always, community speaker series start at noon in room 408 / 410, Meinel Building.

Study Participants Needed
Nathan Lewis is looking for volunteers to participate in his study of measuring the shape of the cornea. He will be testing the effectiveness of a device we built and comparing it to the data obtained from a commercial corneal topographer. He is looking for as many volunteers as possible since a large sample is needed to determine the effectiveness of our test equipment. You are eligible to participate in this study if: 1. You are 18 years old or older, 2. Your cornea is free of scars and/or haze, and 3. You are not pregnant at the time of the initial measurement. There will be no compensation for involvement in the study, but chocolate chip cookies will be provided for all who volunteer! To participate or for more information please contact Nathan Lewis at nlewis@optics.arizona.edu or call to 626-5414.
