Fully-Tensorial Elastic-Wave Mode-Solver in FEniCS for Stimulated Brillouin Scattering Modeling
Marcin Malinowski, Sasan Fathpour
A framework for simulating the elastic-wave modes in waveguides, taking into account the full tensorial nature of the stiffness tensor, is presented and implemented in the open-sou…
Topographically anisotropic photonics for broadband integrated polarization diversity
Jeff Chiles, Tracy Sjaardema, Ashutosh Rao +1
Integrated polarimetric receivers have the potential to define a new generation of lightweight, high-performance instrumentation for remote sensing. To date, on-chip polarization-s…
Second-harmonic generation in single-mode integrated waveguides through mode-shape modulation
Jeff Chiles, Seyfollah Toroghi, Ashutosh Rao +3
A simple and flexible technique for achieving quasi-phase-matching in integrated photonic waveguides without periodic poling is proposed and experimentally demonstrated, referred t…
Second-harmonic generation in periodically-poled thin film lithium niobate wafer-bonded on silicon
Ashutosh Rao, Marcin Malinowski, Amirmahdi Honardoost +4
Second-order optical nonlinear effects (second-harmonic and sum-frequency generation) are demonstrated in the telecommunication band by periodic poling of thin films of lithium nio…
Demonstration of ultra-broadband single-mode and single-polarization operation in T-Guides
Jeff Chiles, Sasan Fathpour
Silica-based anchored-membrane waveguides (T-Guides) are fabricated and characterized from the visible to infrared with streak imaging. It is numerically shown that the T-Guides ca…
Single-mode and single-polarization photonics with anchored-membrane waveguides
Jeff Chiles, Sasan Fathpour
An integrated photonic platform with anchored-membrane structures, the T-Guide, is proposed and numerically investigated. These compact air-clad structures have high index contrast…
