Longitudinal and transverse modulation of electron wave function with light, and its application to electron microscopy

Fabrizio Carbone, Giovanni Maria Vanacore, Ivan Madan, Enrico Pomarico, Gabriele Berruto, Ido Kaminer

Conventional electron microscopy operates with flat electron wave fronts. Employing attenuative or electrostatic phase plates allows transversally modulating the wave front, enhancing cross-sections of particular scattering channels. Utilization of light f ...

X-Band Aom On Chip

Tobias Kippenberg, Anat Siddharth, Junqiu Liu

Silicon Nitride integrated photonic circuits have drawn much attention owing to its ultra-low loss and large Kerr nonlinearity. However, the lack of Pockels effect makes it difficult to be modulated clectro-optically, which posts a major challenge for the ...

A cryogenic electro-optic interconnect for superconducting devices

Tobias Kippenberg, Amir Youssefi, Anton Lukashchuk, Nathan Rafaël Bernier, Liu Qiu, Itay Shomroni

A major challenge to the scalability of cryogenic computing platforms is the heat load associated with the growing number of electrical cable connections between the superconducting circuitry and the room-temperature environment. Compared with electrical c ...

High speed, complex wavefront shaping using the digital micro-mirror device

Demetri Psaltis, Ahmed Ayoub

Digital micro-mirror devices (DMDs) have been deployed in many optical applications. As compared to spatial light modulators (SLMs), they are characterized by their much faster refresh rates (full-frame refresh rates up to 32 kHz for binary patterns) compa ...

High-yield, wafer-scale fabrication of ultralow-loss, dispersion-engineered silicon nitride photonic circuits

Tobias Kippenberg, Rui Ning Wang, Guanhao Huang, Junqiu Liu, Arslan Sajid Raja, Jijun He, Nils Johan Engelsen, Tianyi Liu

Low-loss photonic integrated circuits and microresonators have enabled a wide range of applications, such as narrow-linewidth lasers and chip-scale frequency combs. To translate these into a widespread technology, attaining ultralow optical losses with est ...

Extreme polarization-dependent supercontinuum generation in an uncladded silicon nitride waveguide

Camille Sophie Brès, Eirini Tagkoudi, Caroline Gaëlle Amiot

We experimentally demonstrate the generation of a short-wave infrared supercontinuum in an uncladded silicon nitride (Si3N4) waveguide with extreme polarization sensitivity at the pumping wavelength of 2.1 µm. The air-clad waveguide is specifically designe ...

Dynamics of Soliton Microcomb Self-Injection Locking in a Silicon Nitride Microresonator

Tobias Kippenberg, Andrey Voloshin, Junqiu Liu

We demonstrate a chip-scale 30 GHz single soliton microcomb based on DFB laser locked to a Si3N4 microresonator. We propose novel theoretical and experimental approaches to explain dynamics of self-injection locking, modified by Kerr nonlinearity. (c) 2020 ...

Imaging plasma formation in isolated nanoparticles with ultrafast resonant scattering

Christoph Bostedt, Daniela Rupp, Alessandro Colombo

We have recorded the diffraction patterns from individual xenon clusters irradiated with intense extreme ultraviolet pulses to investigate the influence of light-induced electronic changes on the scattering response. The clusters were irradiated with short ...

From Polarizability to Effective Permittivity of Time-Varying Materials

Romain Christophe Rémy Fleury, Theodoros Koutserimpas, Mohammad Sajjad Mirmoosa

In this talk, we describe excitation of time-varying dipolar particles (time-modulated meta-atoms) by external time-varying fields from a nonstationary and causal perspective. For a time-harmonic excitation, we introduce a complex-valued function, called t ...
