We report on a unique photonic quantum source chip highly integrating four-stage photonic
elements in a lithium niobate (LN) waveguide circuit platform, where an aperiodically poled …

In this Letter, we theoretically study spontaneous parametric downconversion (SPDC) in a
periodically poled structure composed of two linearly uncoupled resonators that are …

We propose and experimentally demonstrate a laser-writing-induced selective chemical
etching (LWISCE) technique for effective micro-fabrication of lithium niobate (LN) crystal …

We propose an ultra-compact, high-performance polarization beam splitter (PBS) on the x-
cut lithium-niobate-on-insulator (LNOI) platform. The device based on asymmetrical …

We propose an optimized low-temperature ion exchange method for fabricating an erbium-
doped lithium niobate on insulator (LNOI) substrate. This method ensures the production of …

We demonstrate an electro-optic (EO) switch or in general, an EO controllable power divider
based on a periodically poled lithium niobate (PPLN) polarization mode converter (PMC) …

We report a broadband adiabatic mode division (de) multiplexer in a thin film lithium niobate
(TFLN) waveguide based on the stimulated Raman adiabatic passage scheme. This …

Broadband spectral filters are highly sought-after in many integrated photonics applications
such as ultra-broadband wavelength division multiplexing, multi-band spectroscopy, and …

On-chip polarization splitter–rotators (PSRs) are crucial components for coherent optical
communication and polarization-division multiplexing systems. Here, we propose and …

Illumination systems play a crucial role in determining the image quality of lens-less images.
In this paper, we propose an illumination system that uses a light guide with a volume …
