Integrated photonics on thin-film lithium niobate

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 Internet to realizing radio-frequency filtering used in our cell phones. This half-century-old material is currently embracing a revolution in thin-film LN integrated photonics. The success of manufacturing wafer-scale, high-quality, thin films of LN on insulator (LNOI), accompanied with breakthroughs in nanofabrication techniques, have made high-performance integrated nanophotonic components possible. With rapid development in the past few years, some of these thin-film LN devices, such as optical modulators and nonlinear wavelength converters, have already outperformed their legacy counterparts realized in bulk LN crystals. Furthermore, the nanophotonic integration enabled ultra-low-loss resonators in LN, which unlocked many novel applications such as optical frequency combs and quantum transducers. In this Review, we cover-from basic principles to the state of the art-the diverse aspects of integrated thinfilm LN photonics, including the materials, basic passive components, and various active devices based on electro-optics, all-optical nonlinearities, and acousto-optics. We also identify challenges that this platform is currently facing and point out future opportunities. The field of integrated LNOI photonics is advancing rapidly and poised to make critical impacts on a broad range of applications in communication, signal processing, and quantum information.

“…As a cavity, it also allows resonant EO modulation [184], with the advantage of reduced electrode size and thus higher RC-limited operating frequency. In addition, optomechanical crystals [142,170,182] that confine both optical and mechanical modes have been demonstrated on suspended LN thin films.…”

“…The phononic, plasmonic, and OMC features are discussed by varying geometrical parameters. As shown, this design results in high VCR rate g 0 (the estimated maximum can exceed 2 × 10 6 Hz), which is predominantly contributed by moving boundary effect, in contrast to that shown in conventional designs (Jiang et al 2019(Jiang et al ,2020Shao et al 2019;Cai et al 2019). As g 0,MB and g 0,PE are out of phase, the following optimization thus focuses on the increment of g 0,MB .…”

“…As further noted that, quite different from conventional phoxonic crystal designs shown in Refs. (Jiang et al 2019(Jiang et al ,2020Shao et al 2019;Cai et al 2019), here the MB effect plays the dominant role in contributing to the overall g 0 , thus it is desirable to increase g 0,MB and suppress g 0,PE . As also demonstrated, this structure allows: a single plasmonic mode coupled to multi-phononic modes, which may find interesting application in multi-mode chip-scale OMC systems (Grutter et al 2015).…”

“…So far the reported OMC strength in LN-based resonator as contributed by photoelastic property is on the order of 10 4 -10 5 Hz (Javerzac-Galy et al 2016a). In LN-based resonator, the OMC is dominated by PE effect as g 0 contributed from MB effect is typically one order of magnitude smaller than that from PE effect (Jiang et al 2019(Jiang et al ,2020Shao et al 2019;Cai et al 2019). To achieve efficient coupling, it is desirable to boost the VCR g 0 .…”

A hybrid plasmonic-phononic cavity design which enables high vacuum coupling rate has been proposed in lithium niobate (LN) phononic crystals (Phncs) that have been perforated by air holes and coated with thin silver film. By tailoring the geometry, optomechanical interaction between the plasmonic modes (produced by the metal/insulator) and the phononic modes (confined by the phononic bandgap effect) is greatly enhanced. Numerical results based on finite-element method (FEM) reveal that in this hybrid plasmonic-phononic design, high vacuum coupling rate that predominantly contributed by moving boundary effect is on the order of 10 6 Hz, which is about one to two orders higher than that contributed by photoelastic effect shown in conventional phoxonic crystal designs. Results evidence how the vacuum coupling rate depends on geometrical parameters like the radius of the defect air hole, the thickness of silver layer, and LN layer. The simultaneous confinement and strong coupling, combined with other advantages as lack of constraint to the refractive index, and integration of piezoelectric material and metal in a chip, this hybrid design may be suitable for non-invasive biological sensing, optomechanically tunable plasmonic heater for drug release and lab-on-chip devices.

A hybrid system that combines cavity magnonics and cavity optomechanics is proposed to facilitate the generation of long‐distance entanglement and enable one‐way steering between magnons and phonons. This configuration involves two directly coupled cavities, with one interacting with magnons and the other coupling with a mechanical oscillator (i.e., phonons). By driving the microwave cavity with a weak squeezed vacuum field generated by a flux‐driven Josephson parametric amplifier, entanglement and one‐way steering can be further enhanced. Moreover, the results demonstrate that magnon–phonon entanglement and one‐way quantum steering exhibit robustness against temperature variations, which has significant implications for quantum information processing and storage.
