Instantaneous quadrature low-coherence interferometry with 3x3 fiber-optic couplers [PDF]
, 2003 We describe fiber-based quadrature low-coherence interferometers that exploit the inherent phase shifts of 3 x 3 and higher-order fiber-optic couplers. We present a framework based on conservation of energy to account for the interferometric shifts in 3 ...

Incoherent lensless imaging via coherency back-propagation
, 2017 The two-point complex coherence function constitutes a complete representation for scalar quasi-monochromatic optical fields. Exploiting dynamically reconfigurable slits implemented with a digital micromirror device, we report on measurements of the ...

Nanobomb optical coherence elastography
Optics Letters, 2018 Wave-based optical elastography is rapidly emerging as a powerful technique for quantifying tissue biomechanical properties due to its noninvasive nature and high displacement sensitivity. However, current approaches are limited in their ability to produce high-frequency waves and highly localized mechanical stress.

Recent progress on the manipulation of single atoms in optical tweezers for quantum computing
, 2007 This paper summarizes our recent progress towards using single rubidium atoms trapped in an optical tweezer to encode quantum information. We demonstrate single qubit rotations on this system and measure the coherence of the qubit.

Optical coherence elastography - OCT at work in tissue biomechanics [Invited].
Biomedical Optics Express, 2017 Optical coherence elastography (OCE), as the use of OCT to perform elastography has come to be known, began in 1998, around ten years after the rest of the field of elastography - the use of imaging to deduce mechanical properties of tissues.
