Science and Innovations Optical Society of America, Express 26 , The larger index contrast in etched waveguides allows for much stronger light confinement. This is a symmetric spectrum but for clarity only the upper portion is displayed. OSA will be closed for the holidays from 21 December Our monolithic LN nanophotonic platform enables dense integration of high-performance active components, opening new avenues for future high-speed, low power and cost-effective communication networks. Error bars show the uncertainty in determining the resonance positions.

The red and blue traces represent the simulated RF effective phase indices of a device under two different cladding circumstances.

Conventional LN modulators however are bulky, expensive and power hungry, and cannot meet the growing demand in modern optical data links. Privacy Terms of Use. Nikogosyan, Nonlinear Optical Crystals: Chip-scale, highly integrated, LN modulators could offer solutions to this problem, yet the fabrication of low-loss devices in LN thin films has been challenging.
