Overcoming stress limitations in SiN nonlinear photonics via a bilayer waveguide
Karl J. McNulty, Shriddha Chaitanya, Swarnava Sanyal +5
Silicon nitride (SiN) formed via low pressure chemical vapor deposition (LPCVD) is an ideal material platform for on-chip nonlinear photonics owing to its low propagation loss and…
Ultra-Low-Loss Silicon Nitride Photonics Based on Deposited Films Compatible with Foundries
Xingchen Ji, Yoshitomo Okawachi, Andres Gil-Molina +4
The fabrication processes of silicon nitride photonic devices used in foundries require low temperature deposition, which typically leads to high propagation losses. Here, we show…
Widely tunable and narrow linewidth chip-scale lasers from deep visible to near-IR
Mateus Corato-Zanarella, Andres Gil-Molina, Xingchen Ji +3
Widely-tunable and narrow-linewidth integrated lasers across all visible wavelengths are necessary to enable on-chip technologies such as quantum photonics, optical trapping, and b…
Measurements and modeling of atomic-scale sidewall roughness and losses in integrated photonic devices
Samantha Roberts, Xingchen Ji, Jaime Cardenas +2
Atomic-level imperfections play an increasingly critical role in nanophotonic device performance. However, it remains challenging to accurately characterize the sidewall roughness…
Exploiting Ultralow Loss Multimode Waveguides for Broadband Frequency Combs
Xingchen Ji, Jae K. Jang, Utsav D. Dave +4
Low propagation loss in high confinement waveguides is critical for chip-based nonlinear photonics applications. Sophisticated fabrication processes which yield sub-nm roughness ar…
Arbitrary control of the polarization and intensity profiles of diffraction-attenuation-resistant beams along their propagation direction
Mateus Corato-Zanarella, Ahmed H. Dorrah, Michel Zamboni-Rached +1
We report on the theory and experimental generation of a class of diffraction-attenuation-resistant beams with state of polarization (SoP) and intensity that can be controlled on d…
Nonparaxial Cartesian and azimuthally symmetric waves with concentrated wavevector and frequency spectra
Mateus Corato-Zanarella, Henrique Corato-Zanarella, Michel Zamboni-Rached
In this paper, we develop a theoretical analysis to efficiently handle superpositions of waves with concentrated wavevector and frequency spectra, allowing an easy analytical descr…
Shaping the longitudinal intensity pattern of Cartesian beams in lossless and lossy media
Mateus Corato-Zanarella, Henrique Corato-Zanarella, Michel Zamboni-Rached
Several applications, such as optical tweezers and atom guiding, benefit from techniques that allow the engineering of optical fields' spatial profiles, in particular their longitu…
