Broadband and Ultra-Compact Adiabatic Coupler Based on Linearly Tapered Silicon Waveguides
Ahmed Bayoumi, Ahmed Khalil, Pol Van Dorpe +8
2x2 couplers are crucial in many photonics applications but are often wavelength-sensitive. Alternative designs could be large, complex, or lossy. We present a broadband ultra-comp…

Engineering high Pockels coefficients in thin-film strontium titanate for cryogenic quantum electro-optic applications
Anja Ulrich, Kamal Brahim, Andries Boelen +13
Materials which exhibit the Pockels effect are notable for their strong electro-optic interaction and rapid response times and are therefore used extensively in classical electro-o…
