An analytical model for lateral contraction of composite laminates subjected to partially uniform tension

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Behzad Dehghan Manshadi

An analytical approach to determine the in-plane stress field and thereby the lateral contraction of composite rectangular plates subjected to partially uniform tension is presented. This approach is based on the Green function hypothesis and is able to ac ...

Continuous-wave vertically emitting photonic crystal terahertz laser

Romuald Houdré, Jérôme Faist, Zhaolu Diao, Christopher Bonzon

Compact semiconductor light sources with high performance continuous-wave (CW) and single mode operation are highly demanded for many applications in the terahertz (THz) frequency range. Distributed feedback (DFB) and photonic crystal (PhC) quantum cascade ...

Seeing through turbidity with harmonic holography [Invited]

Demetri Psaltis, 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 ...

Dynamic bending compensation while focusing through a multimode fiber

Demetri Psaltis, Christophe Moser, Salma Farahi, David Ziegler

Multimode fiber endoscopes have recently been shown to provide sub-micrometer resolution, however, imaging through a multimode fiber is highly sensitive to bending. Here we describe the implementation of a coherent beacon source placed at the distal tip of ...

Increasing the imaging capabilities of multimode fibers by exploiting the properties of highly scattering media

Demetri Psaltis, Christophe Moser, Salma Farahi

We present a design that exploits the focusing properties of scattering media to increase the resolution and the working distance of multimode fiber (MMF)-based imaging devices. Placing a highly scattering medium in front of the distal tip of the MMF enabl ...

Statistics of the disorder-induced losses of high-Q photonic crystal cavities

Romuald Houdré, Vincenzo Savona, Momchil Minkov, Ulagalandha Perumal Dharanipathy

We analyze and compare the effect of fabrication disorder on the quality factor of six well-known high-index photonic crystal cavity designs. The theoretical quality factors for the different nominal structures span more than three orders of magnitude, ran ...

Brillouin optical time-domain analysis over a 240 km-long fiber loop with no repeater

Luc Thévenaz, Sang Hoon Chin, Marcelo Alfonso Soto Hernandez

In this paper we combine the use of optical pulse coding and seeded second-order Raman amplification to extend the sensing distance of Brillouin optical time-domain analysis (BOTDA) sensors. Using 255-bit Simplex coding, the power levels of the Raman pumps ...
