Arrayed waveguide gratings in lithium tantalate integrated photonics

Tobias Kippenberg, Jianqi Hu, Chengli Wang, Shivaprasad Umesh Hulyal, Jiachen Cai

Arrayed waveguide gratings (AWGs) are widely used photonic components for splitting and combining different wavelengths of light. They play a key role in wavelength-division multiplexing (WDM) systems by enabling efficient routing of multiple data channels ...

Photonic solutions help fight climate crisis

Giulia Tagliabue

The mitigation of climate change requires major transformations in the ways we generate energy and operate technologies that release carbon dioxide. Photonic concepts and novel light-driven technologies provide many potential solutions, transforming our cu ...

On the behavior of uniaxial static stress loaded micro-scale fused silica beams at room temperature

Yves Bellouard, Christos Edouardos Athanasiou, Saood Ibni Nazir

The question of whether static stress in fused silica relaxes at room temperature is still under debate. Here, we report experimental data investigating the behavior of fused silica at room temperature when subjected to static tensile stress up to 2 GPa st ...

Optoelectronics based on the spin-valley physics of 2D materials

Juan Francisco Gonzalez Marin

Two-dimensional (2D) materials are atomically thin crystals with exceptional mechanical, electrical and optical properties. Their unique characteristics originating from quantum confinement in the vertical dimension have attracted a strong interest for sci ...

Ultrafast Momentum-Resolved Free-Electron Probing of Optically Pumped Plasmon Thermal Dynamics

Fabrizio Carbone

Current advances in ultrafast electron microscopy make it possible to combine optical pumping of a nanostructure and electron beam probing with sub-Angstrom and femtosecond spatiotemporal resolution. We present a theory predicting that this technique can r ...

High Tuning Range Spiking 1R-1T VO2 Voltage-Controlled Oscillator for Integrated RF and Optical Sensing

Mihai Adrian Ionescu, Teodor Rosca, Fatemeh Qaderi Rahaqi

In this work we propose and experimentally validate a relaxation spiking oscillator architecture with ultra-high tuning range (higher than 400%, from 5KHz to more than 25kHz when the control voltage is varied from 2.5 to 5V) that exploits the reversible me ...

Tuning the response of non-allowed Raman modes in GaAs nanowires

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Federico Matteini, Esther Alarcon Llado, Emanuele Uccelli, Francesca Amaduzzi

We report on the use of photonic resonances in Raman spectroscopy on single nanowires for the enhancement of forbidden modes and the study of the interaction of phonons with free-carriers. This is achieved by suspending nanowire over a trench and detecting ...

Dual-mode temperature compensation technique for laser stabilization to a crystalline whispering gallery mode resonator

Tobias Kippenberg, Albert Schliesser

Frequency stabilization of a diode laser locked to a whispering gallery mode (WGM) reference resonator made of a MgF2 single crystal is demonstrated. The strong thermal dependence of the difference frequency between two orthogonally polarized TE an TM mode ...

Large mode splitting and lasing in optimally coupled photonic-crystal microcavities

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Kirill Atlasov

Coupling of L-type photonic-crystal (PhC) cavities in a geometry that follows inherent cavity field distribution is exploited for demonstrating large mode splitting of up to similar to 10-20 nm (similar to 15-30 meV) near 1 mu m wavelength. This is much la ...

Optical properties of In(Ga)As/GaAs quantum dot-based devices emitting at 1.3[mu]m

Alexander Markus

Self-assembled quantum-dots (QDs) represent a distributed ensemble of zero dimensional structures with a near-singular density of states. Implemented as the active medium in a diode laser their unique properties lead to improved and often novel characteris ...
