Hossein Taghinejad,Mohammad Taghinejad,Alexey Tarasov,Meng-Yen Tsai,Amir H. Hosseinnia,Hesam Moradinejad,Philip M. Campbell,Ali A. Eftekhar,Eric M. Vogel,Ali Adibi +9 more
TL;DR: In this paper, the authors investigated principal roots of heat generation in hybrid cavity-coupled few-atomic-layer-thick 2D transition-metal dichalcogenides (TMDCs) under optical pumping.
Journal ArticleDOI
High-quality silicon on silicon nitride integrated optical platform with an octave-spanning adiabatic interlayer coupler.
TL;DR: A wafer-scale hybrid photonic platform based on the integration of athin crystalline Si layer on top of a thin SiN layer with an ultra-thin oxide buffer layer is developed and a record-low interlayer coupling-loss of 0.02 dB is achieved at 1550 nm telecommunication wavelength window.
