490. Quantum noise in current and future gravitational-wave detectors

Georgia Mansell (Syracuse University)

ANZOS | Photonics and Optics (ANZCOP)

Invited talk

The Laser Interferometer Gravitational-wave Observatory (LIGO) detectors have observed hundreds of compact binary coalescences. Their exquisite sensitivity is achieved through long-baseline interferometry with suspended test masses, among a myriad of other technological aspects. Interferometry is fundamentally limited by the quantum nature of light. At LIGO, quantum noise is mitigated through...

366. The Large Fiber Array Spectroscopic Telescope: trade-off study of high-resolution spectrometer architectures

A combination of large collecting aperture and a highly efficient high-resolution spectrograph is essential for demanding exoplanet science cases, particularly the search for atmospheric biomarkers. We present a design study for a high-resolution spectroscopic facility for the LFAST telescope, an array that combines light from 2640 individual 0.76m telescopes, providing collecting area...

703. Development of Monolithically Integrated Superconducting Nanowire Single Photon Detectors

Dr Alison Goldingay (UNSW)

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

Superconducting Nanowire Single Photon Detectors (SNSPDs) are ultra-sensitive telecommunication-wavelength photodetectors that function on changes in resistance of superconducting nanowires upon photon absorption. SNSPDs are widely considered to be the most sensitive photon detectors available, achieving near unity efficiency including at the telecommunication wavelength of 1550 nm, with...

95. A Novel Arm-Length-Stabilization Scheme for Gravitational Wave Detectors Using AlGaAs/GaAs Coating

Dr JIAN LIU (University of Western Australia)

09/12/2026, 12:00

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

AlGaAs/GaAs crystalline coatings are promising for future gravitational-wave detectors due to their low mechanical loss and superior optical properties. However, their high optical absorption at 532 nm precludes the use of conventional arm-length stabilization schemes based on 532 nm auxiliary lasers.

We present an alternative arm-length stabilization scheme employing an auxiliary laser at...

651. Phase-locked dual soliton crystal microcombs

Dr Chawaphon Prayoonyong (Monash University)

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

Optical microcombs are light sources that can offer a multitude of wavelength lines for many applications ranging from optical communications to spectroscopy. Thanks to their phase coherence, they could replace individual lasers at both transmitter and receiver sides, reducing complexity and easing signal processing since the wavelength lines share the same phase noise. The coherence can be...
