    Area of Science:

    • Astronomy and Astrophysics
    • Optical Instrumentation

    Background:

    • Direct exoplanet imaging is crucial for characterizing atmospheres and surfaces.
    • Ground-based direct imaging faces challenges due to atmospheric turbulence.
    • Existing methods like aperture masking have limitations in contrast and throughput.

    Purpose of the Study:

    • To demonstrate a new generation of photonic pupil-remapping devices for high-contrast exoplanet imaging.
    • To overcome limitations of previous waveguide-based interferometers, specifically unguided light interference and low throughput.
    • To improve the sensitivity and accessibility of the star-to-planet contrast-separation parameter space.

    Main Methods:

    • Development of advanced photonic pupil-remapping devices building on the Dragonfly instrument.
    • Utilizing a waveguide-based interferometer design.
    • Implementing closure phase measurements and adaptive optics (AO) / extreme AO (XAO) systems.

    Main Results:

    • Achieved closure phase measurement scatter of approximately 0.2 degrees.
    • Demonstrated waveguide throughputs exceeding 70%.
    • Reached maximum contrast-ratio sensitivity of 5.3 x 10(-4) with conventional AO and 1.8 x 10(-4) with extreme-AO at 1 lambda/D.
    • Achieved an order of magnitude improvement over conventional pupil-segmenting interferometry.

    Conclusions:

    • The new photonic pupil-remapping devices represent a significant advancement in high-contrast exoplanet imaging.
    • These devices enable exploration of a previously inaccessible parameter space for exoplanet detection and characterization.
    • The demonstrated performance offers a path towards more detailed studies of exoplanetary systems from ground-based telescopes.
