An integrated miniature spectrograph based on waveguide spectral lens

The scaling of next-generation ground- and space-based telescopes presents a critical challenge, as traditional diffraction-grating spectrographs scale in volume and mass roughly with the square of the telescope diameter, leading to prohibitive costs and stability issues. Photonic technology offers a promising solution...

The Earth 2.0 (ET) space mission: science objectives, survey design, and development progress

The Earth 2.0 (ET) mission is a dedicated space observatory designed to discover Earth-sized planets over a broad range of orbital separations and to measure the occurrence rates of terrestrial planets, including Earth 2.0s and free-floating Earth-mass planets. The observatory combines six 28-cm wide-field transit tele...

Adaptive optics in waveguide: conversion from arbitrary multimode to single-mode

Astrophotonics is an emerging field that exploits photonic technologies to enable the miniaturization and integration of astronomical instrumentation. However, the fiber-coupling issue is arguably the most heated debate to determine whether photonics devices could become a practical solution for the development of next...
