Microwave generation and frequency comb in a silicon optomechanical cavity with a full phononic bandgap
Laura Mercadé, Leopoldo L. Martín, Amadeu Griol +2
Cavity optomechanics has become a powerful tool to manipulate mechanical motion via optical fields. When driving an optomechanical cavity with blue-detuned laser the mechanical mot…
Water Fibers
Mark L. Douvidzon, Shai Maayani, Leopoldo L. Martin +1
Fibers constitute the backbone of modern communication and are used in laser surgeries; fibers also genarate coherent X-ray, guided-sound and supercontinuum. In contrast, fibers fo…
Level-crossing and modal structure in microdroplet resonators
Sarah T. Attar, Vladimir Shuvayev, Lev Deych +2
We fabricate a liquid-core liquid-clad microcavity that is coupled to a standard tapered fiber, and then experimentally map the whispering-gallery modes of this droplet resonator.…
Optical humidity sensor based on a liquid whispering-gallery mode resonator
Lucia Labrador-Paez, Kevin Soler-Carracedo, Miguel Hernandez-Rodriguez +3
We experimentally demonstrate the use of a novel liquid state, whispering-gallery-mode optical resonator as a highly sensitive humidity sensor. The optical resonator used consists…
Tweezers controlled resonator
Samuel Kaminski, Leopoldo L. Martin, Tal Carmon
We experimentally demonstrate trapping a microdroplet with an optical tweezer and then enabling it as a microresonator by bringing it close to a tapered fiber coupler. Our tweezers…
Water-Walled Microfluidics Makes an Ultimate Optical Finesse
Shai Maayani, Leopoldo L. Martin, Tal Carmon
Liquids serve microcavity research ever since Ashkins studies on optical resonances in levitating droplets to recent optofluidic resonators. Droplets can provide optical quality fa…
On the transition from photoluminescence to thermal emission and its implication on solar energy conversion
Assaf Manor, Leopoldo L. Martin, Carmel Rotschild
Photoluminescence (PL) is a fundamental light-matter interaction, which conventionally involves the absorption of energetic photon, thermalization and the emission of a red-shifted…
Optical Refrigeration for Ultra-Efficient Photovoltaics
Assaf Manor, Leopoldo L. Martin, Carmel Rotschild
Improving the conversion efficiency of solar energy to electricity is most important to mankind. For single-junction photovoltaic solar-cells, the Shockley-Queisser thermodynamic e…
