Systematic Design and Demonstration of Multipole, Coupled-Cavity Integrated Photonic Bandpass Filters with High FSR, High-Q Single-Mode Microresonators in Low-Loss Silicon Nitride Platform
Amir H Hosseinnia, Abdel Karim El Amili, Yu-hung Lai +4
Tunable, low-loss, narrowband, and frequency-stabilized filters play a critical role in the realization of transceivers for efficient signal processing in telecommunications and se…
Photonic Crystal Microring Resonators on a Hybrid Silicon Nitride-on-Lithium Niobate Platform
Zhongdi Peng, Rakesh Krishna, Xi Wu +3
Photonic-crystal resonators (PhCRs) have been widely used in nonlinear integrated photonics for frequency engineering applications. A microwave-assisted frequency converter based o…
Racetrack microresonator based electro-optic phase shifters on a 3C-silicon-carbide-on-insulator platform
Tianren Fan, Xi Wu, Sai R. M. Vangapandu +3
We report the first demonstration of integrated electro-optic (EO) phase shifters based on racetrack microresonators on a 3C-silicon-carbide-on-insulator (SiCOI) platform working a…
ITO-Based Microheaters for Reversible Multi-Stage Switching of Phase-Change Materials: Towards Miniaturized Beyond-Binary Reconfigurable Integrated Photonics
Hossein Taghinejad, Sajjad Abdollahramezani, Ali A. Eftekhar +6
Inducing a large refractive-index change is the holy grail of reconfigurable photonic structures, a goal that has long been the driving force behind the discovery of new optical ma…
Wideband bright soliton frequency comb generation at optical telecommunication wavelength in a thin SiN film
Ali Eshaghian Dorche, Amir Hossein Hosseinnia, Ali Asghar Eftekhar +1
Bright-soliton frequency comb generation in a thin-film silicon nitride (SiN) microresonator at optical telecommunication wavelengths is numerically demonstrated using our recently…
Nonlinear Raman Shift Induced by Exciton-to-Trion Transformation in Suspended Trilayer MoS2
Hossein Taghinejad, Mohammad Taghinejad, Alexey Tarasov +6
Layered two-dimensional (2D) semiconductors such as molybdenum disulfide (MoS2) have recently attracted remarkable attention because of their unique physical properties. Here, we u…
Calculation of Band Structure Using Local Sampling and Green's Functions
Milad Khoshnegar, Sina Khorasani, Amirhossein Hosseinnia
A new method for calculation of band structure has been proposed based on the Green's function theory and local sampling. Potential energy in the Hamiltonian of Schrodinger's equat…
