Photogalvanic second harmonic generation in Si3N4 for 1 Hz level on-chip metrology and spectroscopy
Andrei Diakonov, Roy Zektzer, Xiyuan Lu +2
The coherent photogalvanic (PG) effect induces an effective nonlinearity in natively silicon nitride integrated photonics, unlocking pathways toward chip-scale…
Enabling atom-clad waveguide operation in a microfabricated alkali vapor-photonic integrated circuit
Rahul Shrestha, Khoi Tuan Hoang, Peter Riley +5
Integrating alkali atomic vapors with nanophotonic devices offers a scalable route to quantum technologies that leverage strong atom-photon interactions. While there have been many…
Full spectral response of grating-induced loss in photonic crystal microrings
Daniel Pimbi, Yi Sun, Roy Zektzer +2
Photonic crystal microrings (PhCRs) have emerged as powerful and versatile platforms for integrated nonlinear photonics, offering precise control over frequency and phase matching…
Laser injection locking and nanophotonic spectral translation of electro-optic frequency combs
Roy Zektzer, Ashish Chanana, Xiyuan Lu +2
High-resolution electro-optic frequency combs (EO combs) consisting of thousands to millions of comb teeth across a bandwidth between 1 GHz to 500 GHz are powerful tools for atomic…
