Off-chip beam steering with a one-dimensional optical phased array on silicon-on-insulator
TL;DR: An integrated approach is followed in which a 1D optical phased array is fabricated on silicon-on-insulator in which continuous thermo-optical steering of 2.3 degrees and wavelength steering of 14.1 degrees is reported.
Journal ArticleDOI

TL;DR: In this paper, the advantages and challenges associated with these two material platforms are discussed, and the case of dispersive spectrometers, which are widely used in various silicon photonic applications, is presented.
Journal ArticleDOI
Refractive index sensing with an air-slot photonic crystal nanocavity
TL;DR: The high quality factor approximately 2.6x10(4) of the cavity, along with a strong overlap between the resonant mode and the hollow core region, allows for an experimental sensitivity of 510nm per refractive index unit (RUI) and a detection limit below 1x10(-5)RUI.
