An easy-to-fabricate but very efficient fiber-to-waveguide coupler is theoretically analyzed and experimentally demonstrated. In this design, light from a single-mode fiber can be butt coupled into a single-mode high-index-contrast Si3N4/SiO2 wavegui

We demonstrate a coupler with an ultra-broadband high coupling efficiency of 96% at 1550 nm, and > 90% from 1450 nm to 1650 nm experimentally. The coupler also features ease of cleaving and large alignment tolerances of 3.8 μm horizontally and 3.6

We demonstrate a Complex Waveguide Bragg Grating (CWBG) which can realize any arbitrary transmission spectrum. As a proof of demonstration, a CWBG which removes 20 randomly-distributed spectral notches have been theoretically designed and experimenta

Astrophotonics is the next-generation approach that provides the means to miniaturize near-infrared (NIR) spectrometers for upcoming large telescopes and make them more robust and inexpensive. The target requirements for our spectrograph are: a resol

We demonstrate both a 93% coupling efficiency from a single-mode fiber to a single-mode reasonably confined silicon nitride waveguide, and a complex Waveguide Bragg Grating based on a Layer Peeling/Adding Algorithm.
