DC-to-GHz Modulation In Microring Modulators Using Ferroelectric Nematic Liquid Crystal-on-Silicon in a Foundry Photonic Process
Iman Taghavi, Alexander Tofini, Edward K. Leung +4
Silicon-organic hybrid (SOH) platforms exhibit exceptional electro-optic (EO) properties, including high-speed operation, low energy consumption, and compact footprints. However, t…
Neuromorphic Photonic Computing with an Electro-Optic Analog Memory
Sean Lam, Ahmed Khaled, Simon Bilodeau +5
In neuromorphic photonic systems, device operations are typically governed by analog signals, necessitating digital-to-analog converters (DAC) and analog-to-digital converters (ADC…
Optoelectronic Physical Unclonable Functions and Reservoir-Inspired Computation with Low Symmetry Integrated Photonics
Farhan Bin Tarik, Yingjie Lao, Mustafa Hammood +5
Emerging applications of photonics in computing, sensing, and security increasingly demand complex input-output behaviors, including highly nonlinear transformations of optical sig…
Impact of Oxygen Plasma Surface Treatment on Photoresist Adhesion in BaTiO3-Based Photonic Device Fabrication
Weiyou Kong, Weijia Kong, Lukas Chrostowski +1
Oxygen-plasma pre-cleans are routine before fabrication, but on BaTiO3 thin films we observed catastrophic photoresist lift-off during mild rinsing and sonication. To explain the f…
Isolator-Free Laser Operation Enabled by Chip-Scale Reflections in Zero-Process-Change SOI
Omid Esmaeeli, Lukas Chrostowski, Sudip Shekhar
The isolation-free operation of photonic integrated circuits enables dense integration, reducing packaging costs and complexity. Most isolator replacements require a change in the…
GHz-rate optical phase shift in light matter interaction-engineered, silicon-ferroelectric nematic liquid crystals
Iman Taghavi, Omid Esmaeeli, Sheri Jahan Chowdhury +10
Organic electro-optic materials have demonstrated promising performance in developing electro-optic phase shifters. Their integration with other silicon photonic processes, nanofab…
