Abstract (EN) A major focus is on integrated Silicon-based optoelectronics for the creation of
low-cost photonics for mass-market applications. Especially, the growing demand for …

We report a critical assessment of the use of non-uniform gratings for enhancing light
coupling to photonic integrated circuits (PICs). Grating couplers, performing as a very …

We compute the fiber-to-chip coupling efficiency of grating couplers for fiber mode
diameters≤ 10µm. Modeling shows that high coupling efficiency (− 1.5 dB loss) can be …

Grating couplers are the best solution for testing nano-photonic circuits. Their main benefit is
that they allow access via an optical fiber from the top and therefore there is no need to dice …
