Dispersion Control in Micromechanical Evanescent Optical Modulators
Karl Johnson, John Hong, Tallis Chang +8
Efficient, low-loss, and versatile optical modulators are a critical ingredient for practical integrated photonic systems. Modulators based on micro-electromechanical systems (MEMS…
Interferometric modal splitting enables a broadband, dual-polarization on-chip spectrometer
Karl Johnson, Vladimir Fedorov, Dmitrii Belogolovskii +3
The modal dispersion of waveguides often limits integrated photonic devices to operation with a single polarization state. This presents a challenge for sensing and spectroscopy ap…
Large Bidirectional Refractive Index Change in Silicon-rich Nitride via Visible Light Trimming
Dmitrii Belogolovskii, Md Masudur Rahman, Karl Johnson +6
Phase-sensitive integrated photonic devices are highly susceptible to minor manufacturing deviations, resulting in significant performance inconsistencies. This variability has lim…
Information Processing in Hybrid Photonic Electrical Reservoir Computing
Prabhav Gaur, Chengkuan Gao, Karl Johnson +3
Physical Reservoir Computing (PRC) is a recently developed variant of Neuromorphic Computing, where a pertinent physical system effectively projects information encoded in the inpu…
