Optical interconnects have been recognized as the most promising solution to accelerate data transmission in artificial intelligence era. Benefiting from their cost-effectiveness, compact dimensions, and wavelength multiplexing capability, silicon microring resonator modulators emerge a compelling scalable means for optical modulation. However, inherent trade-off between bandwidth modulation efficiency hinders device performance. Here we demonstrate dense division modulator array on chip...

InAlAs digital alloy avalanche photodiodes exhibit lower excess noise than those fabricated from conventional random material. Experiment and Monte Carlo simulation both show that relative to the ionization probability for electrons is slightly while of holes greatly suppressed. We propose suppression carrier in alloys happens because creation minibands localize carriers. The difference between conduction bands valence comes scattering path.
Space and guided electromagnetic waves, as widely known, are two crucial cornerstones in extensive wireless integrated applications respectively. To harness the cornerstones, radiative devices usually developed parallel based on same physical principles. An emerging mechanism, i.e., anti-parity-time (APT) symmetry originated from non-Hermitian quantum mechanics, has led to fruitful phenomena harnessing waves. However, it is still absent space Here, we propose a plasmonic APT design...
