Lithium niobate (LN), an outstanding and versatile material, has influenced our daily life for
decades—from enabling high-speed optical communications that form the backbone of the …

Lithium niobate (LN) has experienced significant developments during past decades due to
its versatile properties, especially its large electro-optic (EO) coefficient. For example, bulk …

Optical isolators today are exclusively built on magneto-optic principles but are not readily
implemented within photonic integrated circuits. So far, no magnetless alternative …

This paper presents a review of the radio frequency thin-film lithium niobate (LiNbO 3) based
acoustic microsystems. Thanks to their high electromechanical coupling (k 2), low loss, and …

A highly efficient on-chip acousto-optic modulator is as a key component and occupies an
exceptional position in microwave-to-optical conversion. Homogeneous thin-film lithium …

We propose and demonstrate experimentally the strong dissipative acousto-optic interaction
between a suspended vibrating microfiber and a whispering-gallery microcavity. On the one …

The ability to manipulate the refractive index is a fundamental principle underlying
numerous photonic devices. Various techniques exist to modify the refractive index across …

Optical nonreciprocity plays a key role in almost every optical system, directing light flow and
protecting optical components from backscattered light. Controllable forms of on-chip …

The integration of qubits with long coherence times and functional quantum devices on a
single chip, and thus the realization of an all-solid-state quantum computing chip, is an …

The lithium niobate on insulator devices confine the light field to submicron size in
monocrystalline lithium niobate, to achieve ultra-strong electro-optical interaction and …
