High-channel-count 20 GHz passively mode locked quantum dot laser directly grown on Si with 4.1 Tbit/s transmission capacity
Songtao Liu, Xinru Wu, Daehwan Jung +5
Low cost, small footprint, highly efficient and mass producible on-chip wavelength-division-multiplexing (WDM) light sources are key components in future silicon electronic and pho…
Vernier spectrometer using counter-propagating soliton microcombs
Qi-Fan Yang, Boqiang Shen, Heming Wang +8
Acquisition of laser frequency with high resolution under continuous and abrupt tuning conditions is important for sensing, spectroscopy and communications. Here, a single microres…
Extended polarized semiclassical model for quantum-dot cavity QED and its application to single-photon sources
H. J. Snijders, D. N. L. Kok, M. F. van de Stolpe +7
We present a simple extension of the semi-classical model for a two-level system in a cavity, in order to incorporate multiple polarized transitions, such as those appearing in neu…
Probing interacting two-level systems with rare-earth ions
Dapeng Ding, David van Driel, Lino M. C. Pereira +8
Two-level systems (TLS) in amorphous materials limit coherence times of a number of solid-state quantum devices. Interactions between TLS become prominent below 100 mK, but the cou…
Meta-surface-enabled ultra-sharp multimode waveguide bends on silicon
Hao Wu, Chenlei Li, Lijia Song +3
Mode-division-multiplexing (MDM) is attractive as a means to increase the link capacity of a single wavelength for optical interconnects via the use of multiple mode-channels in mu…
Diffraction limited centimeter scale radiator: metasurface grating antenna for phased array LiDAR
Weiqiang Xie, Jinxi Huang, Tin Komljenovic +2
In this paper, we demonstrate a radiation-strength-chirped metasurface centimeter-long grating antenna, whose beam quality is approaching the diffraction limit in its footprint wit…
