Combinatorial High-Vacuum Chemical Vapor Deposition of Lithium Niobate Thin Films

Ali Dabirian

Lithium niobate is a key material for photonics with applications in optical modulators and light frequency converters. Present lithium niobate optical devices are realized in bulk lithium niobate single crystals while interests in higher integration and a ...

Combinatorial Discovery and Optimization of Amorphous HfO2-Nb2O5 Mixture with Improved Transparency

Paul Muralt, Patrik Willi Hoffmann, Estelle Wagner, Giacomo Benvenuti, Silviu Cosmin Sandu, Bamdad Afra, Ali Dabirian, Yury Kuzminykh, Scott Harada

Combinatorial high vacuum chemical vapor deposition (HV-CVD) of mixed HfO2-Nb2O5 thin films has been demonstrated to yield amorphous layers at substrate temperatures where individually deposited pure HfO2 and Nb2O5 films are polycrystalline. Spectroscopic ...

Determination of local refractive index variations in thin films by heterodyne interferometric scanning near-field optical microscopy

Patrik Willi Hoffmann, Giacomo Benvenuti, Maria-Pilar Bernal, Ali Dabirian, Yury Kuzminykh

We report on a heterodyne interferometric scanning near-field optical microscope developed for characterizing, at the nanometric scale, refractive index variations in thin films. An optical lateral resolution of 80 nm (lambda/19) and a precision smaller th ...
