Fabrication of Sub-Micron Polymer Waveguides through Two-Photon Polymerization in Polydimethylsiloxane

Demetri Psaltis, Christophe Moser, Ye Pu, Giulia Panusa, Jieping Wang

Flexible ultra-compact low-loss optical waveguides play a vital role in the development of soft photonics. The search for suitable materials and innovative fabrication techniques to achieve low loss long polymer optical waveguides and interconnects has pro ...

Optical proximity sensing system for atraumatic cochea implant surgery

Demetri Psaltis, Ye Pu, Christophe Moser, Ye Pu

The design of a proximity sensor to be integrated into cochlea implants is described. The sensor allows the anticipation of contact between the cochlear implant and intracochlear structures, including the cochlear canal wall and basilar membrane, providing ...

Two-dimensional polymeric structures and method for producing thereof

Demetri Psaltis, Ye Pu, Jeffrey Alan Hubbell, Ye Pu, Marcin Stefan Zielinski

The present invention relates to polymeric structures, in the form of flat membrane-like surfaces or micro- nanostructures such as capsules, characterized in that it comprises a substantially two-dimensional layer of covalently-bonded monomers of R-substit ...

Second-harmonic radiating imaging probes and harmonic holography

Demetri Psaltis, Ye Pu, Ye Pu

Compared with other imaging probes such as fluorescent dyes and quantum dots, second-harmonic radiating imaging probes (SHRIMPs) provide a unique ultrafast, coherent optical contrast that is free of photobleaching and emission intermittency. Using the seco ...

Imaging blood cells through scattering biological tissue using speckle scanning microscopy

Demetri Psaltis, Ye Pu, Ye Pu, Xin Yang

We demonstrate imaging of blood cells enclosed in chicken skin tissue using speckle scanning microscopy (SSM). Clear images of multiple cells were obtained with subcellular resolution and good image fidelity, provided that the object dimension was smaller ...

Tissue and cellular imaging

Demetri Psaltis, Ye Pu, Ye Pu, Chia-Lung Hsieh, Xin Yang

Systems and methods for imaging ear tissue include: directing illumination radiation to pass through an intact biological structure and be incident on ear tissue that does not include an exogenous fluorophore, at a plurality of locations, the illumination ...

Seeing through turbidity with harmonic holography [Invited]

Demetri Psaltis, Ye Pu, Ye Pu

The ability to see inside the body noninvasively is indispensable in modern biology and medicine. Optical approaches to such abilities are of rapidly growing interest because of their nonionizing nature and low cost. However, the problem of opacity due to ...

Two-photon microscopy of the mouse cochlea in situ for cellular diagnosis

Demetri Psaltis, Ye Pu, Ye Pu, Chia-Lung Hsieh, Xin Yang

Sensorineural hearing loss is the most common type of hearing loss worldwide, yet the underlying cause is typically unknown because the inner ear cannot be biopsied today without destroying hearing, and intracochlear cells have not been imaged with resolut ...

Three-dimensional scanning microscopy through thin turbid media

Demetri Psaltis, Ye Pu, Ye Pu, Chia-Lung Hsieh, Xin Yang

We demonstrate three-dimensional imaging through a thin turbid medium using digital phase conjugation of the second harmonic signal emitted from a beacon nanoparticle. The digitally phase-conjugated focus scans the volume in the vicinity of its initial pos ...
