Gravitational waves from rapid structure formation on microscopic scales before matter-radiation equality

Kavli Affiliate: Misao Sasaki | First 5 Authors: Marcos M. Flores, Alexander Kusenko, Misao Sasaki, , | Summary: The existence of scalar fields can be probed by observations of stochastic gravitational waves. Scalar fields mediate attractive forces, usually stronger than gravity, on the length scales shorter than their Compton wavelengths, which can be non-negligible in […]

Platform-agnostic waveguide integration of high-speed photodetectors with evaporated tellurium thin films

Kavli Affiliate: Ali Javey | First 5 Authors: Geun Ho Ahn, Alexander D. White, Hyungjin Kim, Naoki Higashitarumizu, Felix M. Mayor | Summary: Many attractive photonics platforms still lack integrated photodetectors due to inherent material incompatibilities and lack of process scalability, preventing their widespread deployment. Here we address the problem of scalably integrating photodetectors in […]
