Much of the progress in astronomy has been driven by instrumental developments, from the
first telescopes to fiber fed spectrographs. In this review, we describe the field of …

One promising application of photonics to astronomical instrumentation is the miniaturization
of near-infrared (NIR) spectrometers for large ground-and space-based astronomical …

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 …

Integrated photonic spectrographs offer an avenue to extreme miniaturization of
astronomical instruments, which would greatly benefit extremely large telescopes and future …

Arrayed waveguide gratings with reusable delay lines (RDL-AWGs) are demonstrated as
high resolving power integrated photonic spectrometers. One of the devices is 71 times …

We present a statistical analysis of arrayed waveguide gratings (AWGs) in the presence of
phase errors in the optical waveguides caused by fabrication process variations. Important …

Astrophotonics is the application of versatile photonic technologies to channel, manipulate,
and disperse guided light from one or more telescopes to achieve scientific objectives in …

With the upcoming extremely large telescopes (ELTs), the volume, mass, and cost of the
associated spectro-graphs will scale with the telescope diameter. Astrophotonics offers a …
