1.06μm-1.35μm coherent pulse generation by a synchronously-pumped phosphosilicate Raman fiber laser
(OSA, 2017)Summary form only given. Rare-earth-doped fiber lasers are attractive for microscopy and imaging applications and have developed over the past decades rapidly. They are unable to cover near-infra-red region entirely and ... -
Applying the principle of orthogonality of high dimensional random vectors to obtain high-density, large-volume 3D holographic display
(OSA, 2018)The efforts toward truly 3D displays are far from exploiting the full potential of holography. Here, we apply the principle of orthogonality of high dimensional random vectors to obtain unprecedented dense, large volume holograms. -
Breaking crosstalk limits to dynamic holography using orthogonality of high-dimensional random vectors
(Nature Publishing Group, 2019)Holography is the most promising route to true-to-life three-dimensional (3D) projections, but the incorporation of complex images with full depth control remains elusive. Digitally synthesized holograms1,2,3,4,5,6,7, which ... -
Buried waveguides written deep inside silicon
(OSA, 2017)Summary form only given. Silicon waveguides are widely used as optical interconnects and they are particularly important for Si-photonics. Si-based devices, along with other optical elements, are entirely fabricated on the ... -
Computer-generated holograms embedded in bulk silicon with nonlinear laser lithography
(IEEE, 2016)Recently, we have showed a direct laser writing method to form subsurface structures inside silicon by exploiting nonlinear interactions. Here, we demonstrate utilization of this phenomenon to create computer-generated ... -
Holograms deep inside Silicon
(Optical Society of America, 2016)Through the Nonlinear Laser Lithography method, we demonstrate the first computer generated holograms fabricated deep inside Silicon. Fourier and Fresnel holograms are fabricated buried inside Si wafers, and a generation ... -
Intracavity optical trapping of microscopic particles in a ring-cavity fiber laser
(Nature Publishing Group, 2019-06)Standard optical tweezers rely on optical forces arising when a focused laser beam interacts with a microscopic particle: scattering forces, pushing the particle along the beam direction, and gradient forces, attracting ... -
Optical waveguides written deep inside silicon by femtosecond laser
(OSA, 2017)Summary form only given. Photonic devices that can guide, transfer or modulate light are highly desired in electronics and integrated silicon photonics. Through the nonlinear processes taking place during ultrafast ... -
Rich complex behaviour of self-assembled nanoparticles far from equilibrium
(Nature Publishing Group, 2017)A profoundly fundamental question at the interface between physics and biology remains open: what are the minimum requirements for emergence of complex behaviour from nonliving systems? Here, we address this question and ... -
Self-dissimilarity, irreversibility and robustness in mode-locked fiber oscillators
(OSA, 2018)We introduce self-dissimilarity as measure of phase space complexity and predictor of robustness against perturbations. As nonlinearity increases, phase space becomes a random fractal, just before critical transitions. ... -
Two-photon excitation of quantum dots in 3D via stacked fresnel hologram algorithm
(OSA, 2017)Quantum dots are engineered to have nanometers dimensions. The ability to specify the diameter and the material of the quantum dots allow us tune the absorption and emission properties. This results in extensive capabilities ...
