Lightwave Circuits in Lithium Niobate through Hybrid Waveguides with Silicon Photonics

Journal Article Weigel, Peter O. ; Savanier, Marc ; DeRose, Christopher T. ; ... - Scientific Reports

Here, we demonstrate a photonic waveguide technology based on a two-material core, in which light is controllably and repeatedly transferred back and forth between sub-micron thickness crystalline layers of Si and LN bonded to one another, where the former is patterned and the latter is not. In this way, the foundry-based wafer-scale fabrication technology for silicon photonics can be leveraged to form lithium-niobate based integrated optical devices. Using two different guided modes and an adiabatic mode transition between them, we demonstrate a set of building blocks such as waveguides, bends, and couplers which can be used to route light underneathmore »« less

A heterogeneously integrated silicon photonic/lithium niobate travelling wave electro-optic modulator

Journal Article Boynton, Nicholas ; Cai, Hong ; Gehl, Michael ; ... - Optics Express

Silicon photonics is a platform that enables densely integrated photonic components and systems and integration with electronic circuits. Depletion mode modulators designed on this platform suffer from a fundamental frequency response limit due to the mobility of carriers in silicon. Lithium niobate-based modulators have demonstrated high performance, but the material is difficult to process and cannot be easily integrated with other photonic components and electronics. In this manuscript, we simultaneously take advantage of the benefits of silicon photonics and the Pockels effect in lithium niobate by heterogeneously integrating silicon photonic-integrated circuits with thin-film lithium niobate samples. We demonstrate the mostmore »« less

Improved fabrication of scalable hybrid silicon nitride–thin-film lithium niobate electro-optic modulators

Journal Article Mere, Viphretuo ; Valdez, Forrest ; Mookherjea, Shayan - Journal of the Optical Society of America. Part B, Optical Physics

Strategies for improved fabrication of integrated thin-film lithium niobate electro-optic (EO) Mach–Zehnder modulators (MZMs) are reported using scalable processes and designs. The MZM devices utilize direct bonding of unetched and unpatterned thin-film lithium niobate to patterned and planarized silicon photonic microchips. The latter contains silicon nitride waveguide structures of various widths that are used to form hybrid modes that are suitable for high-bandwidth low-voltage EO modulators based on Pockels effect. We report that the incorporation of appropriately designed outgassing channels and certain modifications to key processing steps helped achieve a greater than 99% reduction in void density during bonding.

Formation of waveguide channels by dark spatial solitons in a planar waveguide optically induced in a lithium niobate crystal

Journal Article Shandarov, V M ; Shandarova, K V - Quantum Electronics (Woodbury, N.Y.)

The formation of optical waveguide channels is experimentally demonstrated upon the photorefractive self-action of a phased light beam in a planar waveguide optically induced in an iron-doped lithium niobate crystal. Planar and channel waveguides were produced by using a 633-nm He-Ne laser with output powers 1 mW and {approx}10 {mu}W, respectively. (waveguides)
