Strong Optical-Mechanical Coupling in a Vertical GaAs/AlAs Microcavity for Subterahertz Phonons and Near-Infrared Light
(American Physical Society, 2013-01)
We show that distributed Bragg reflector GaAs/AlAs vertical cavities designed to confine photons are automatically optimal to confine phonons of the same wavelength, strongly enhancing their interaction. We study the ...
Self-aligning CMOS photodetector sensor for application on an NDB-based optical encoder
(Optical Society of America, 2019-11)
In this work, a complementary metal–oxide–semiconductor (CMOS) photodetector specifically designed to be used in a non-diffracting-beam (NDB) optical encoder is introduced. The sensor is aimed to address the critical ...

Nd:YAG Laser Irradiation effect on apical intracanal dentin-a microleakage and SEM evaluation
(2011-10-24)
The purpose of this in vitro study was to evaluate the effect of neodymium:yttrium-aluminum-garnet (Nd:YAG) laser irradiation on intracanal dentin surface by SEM analysis and its interference in the apical seal of filled ...

Optoelectronic forces with quantum wells for cavity optomechanics in GaAs/AlAs semiconductor microcavities
(American Physical Society, 2018-05)
Radiation pressure, electrostriction, and photothermal forces have been investigated to evidence backaction, nonlinearities, and quantum phenomena in cavity optomechanics. We show here through a detailed study of the ...
