High-performance Hybrid Lithium Niobate Electro-optic Modulators Integrated with Low-loss Silicon Nitride Waveguides on a Wafer-scale Silicon Photonics Platform
Arif Rahman, Forrest Valdez, Viphretuo Mere +3
Heterogeneously-integrated electro-optic modulators (EOM) are demonstrated using the hybrid-mode concept, incorporating thin-film lithium niobate (LN) by bonding with silicon nitri…
100 GHz Bandwidth, 1 Volt Near-infrared Electro-optic Mach-Zehnder Modulator
Forrest Valdez, Viphretuo Mere, Shayan Mookherjea
An integrated hybrid thin-film lithium niobate (TFLN) electro-optic Mach-Zehnder modulator (MZM) is shown at near-infrared wavelengths. The design uses TFLN bonded to planarized si…
Integrated O- and C-band Silicon-Lithium Niobate Mach-Zehnder Modulators with 100 GHz Bandwidth, Low Voltage, and Low Loss
Forrest Valdez, Viphretuo Mere, Xiaoxi Wang +1
Broadband integrated thin-film lithium niobate (TFLN) electro-optic modulators (EOM) are desirable for optical communications and signal processing in both the O-band (1310 nm) and…
110 GHz, 110 mW Hybrid Silicon-Lithium Niobate Mach-Zehnder Modulator
Forrest Valdez, Viphretuo Mere, Xiaoxi Wang +9
High bandwidth, low voltage electro-optic modulators with high optical power handling capability are important for improving the performance of analog optical communications and RF…
Independently reconfigurable internal loss and resonance-shift in an interferometer-embedded optical cavity
Aneesh Dash, Viphretuo Mere, S. K. Selvaraja +1
Optical cavities find diverse uses in lasers, frequency combs, optomechanics, and optical signal processors. Complete reconfigurability of the resonant frequency as well as the los…
Efficient and Tunable Strip-to-Slot Fundamental Mode Coupling
Viphretuo Mere, Rakshitha Kallega, Shankar Kumar Selvaraja
We present a novel photonic wire-to-slot waveguide coupler in SOI. The phase matching between a wire and slot mode is achieved using a mode transformer. The architecture consists o…
