What to expect
Lithium niobate’s electro-optic (Pockels) effect has been known for over 80 years, yet it remains at the forefront of photonics research. This talk explores how technological advances have transformed electro-optic (EO) modulators from bulky components to compact, high-performance devices based on thin-film lithium niobate (LNTF). Through a historical perspective, we’ll examine the key metrics that have driven this evolution—energy efficiency, bandwidth, and footprint—and the trade-offs involved.
Outline:
• I. Bulk LiNbO₃ Devices
Introduction to the index ellipsoid, common configurations, and current uses.
• II. Standard LiNbO₃ Waveguides
Overview of traditional waveguiding technologies, their evolution, and essential performance parameters for EO modulation.
• III. LNOI and TFLN-Based EO Components
How thin-film platforms enable broadband, low-power EO modulation, with a focus on Mach-Zehnder modulators as a key example.
• IV. Miniaturization
A look at the emerging role of EO photonic crystals in pushing the limits of integration.
