Accurate Measurement of Dynamic ON-Resistance in GaN Transistors at Steady-State

Elison de Nazareth Matioli, Hongkeng Zhu

Accurate characterization of the dynamic ON-resistance (RON) degradation is important to predict conduction losses for gallium nitride high-electron-mobility transistors (GaN HEMTs). However, even for the same device, many inconsistent results of dynamic R ...

Population receptive fields isolate or combine target and flankers in (un)crowding

Michael Herzog, Bogdan Draganski, Ayberk Ozkirli, Maya Anna Jastrzebowska

Crowding by neighboring elements leads to the deterioration of target discrimination. This phenomenon is traditionally explained with feedforward, hierarchical models. In these models, a “bottleneck” at the earliest stages of visual processing causes an ir ...

Platicon microcomb generation using laser self-injection locking

Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Wenle Weng, Yang Liu, Jijun He, Miles Henry Anderson

The past decade has witnessed major advances in the development and system-level applications of photonic integrated microcombs, that are coherent, broadband optical frequency combs with repetition rates in the millimeter-wave to terahertz domain. Most of ...

The role of population receptive field size and recurrent processing in learning to “de-crowd”

Michael Herzog, Bogdan Draganski, Ayberk Ozkirli, Maya Anna Jastrzebowska

In crowding, the perception of a target is impeded by surrounding clutter. While traditional models are feedforward and local, there is increasing behavioral and neural evidence for a critical role of recurrent processing across the visual hierarchy in cro ...

Isolate or combine: population receptive field size in (un)crowding

Michael Herzog, Bogdan Draganski, Ayberk Ozkirli, Maya Anna Jastrzebowska

Crowding, the deterioration of object recognition in clutter, is traditionally explained with models that are hierarchical, feedforward and local. These models suggest that a “bottleneck” at the earliest stages of visual processing leads to an irretrievabl ...

Resonant Supercontinuum Generation in Normal and Anomalous Dispersion

Tobias Kippenberg, Junqiu Liu, Wenle Weng, Tobias Herr, Miles Henry Anderson

We demonstrate broadband resonant supercontinuum generation based on stable bright soliton formation in Si3N4 microresonators with either anomalous or normal dispersion. The frequency combs have an electronically detectable repetition rate of 28 GHz, and s ...

Massively parallel coherent laser ranging using a soliton microcomb

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Erwan Guillaume Albert Lucas, Wenle Weng, Anton Lukashchuk

Coherent ranging, also known as frequency-modulated continuous-wave (FMCW) laser-based light detection and ranging (lidar)(1) is used for long-range three-dimensional distance and velocimetry in autonomous driving(2,3). FMCW lidar maps distance to frequenc ...
