Abstract

The Frequency Standards and Metrology Research Group at the University of Western Australia have been developing some of the world's most ultra-precise measurements at microwave frequencies since the 1990s. This paper reviews past and intended future work with applications to low temperatures where quantum effects become important.

An ultra-stable microwave transfer technique for the ACES and future space missions

We present an actuation technique for suppressing uncorrelated noise between two optical frequencies to obtain ultra-stable microwave frequency dissemination over optical fibre. This technique will enable dual optical and microwave frequency transfer between the University of Western Australia and Yarragadee Satellite Laser Ranging station, which has application for the Atomic Clock Ensemble in Space (ACES) mission and other precision navigation and timing technologies. We build on the technique presented in [1], which demonstrates microwave transfer stability of 10−14 at 1s integration time by stabilising the group delay of an two correlated optical signals. A second actuator has been developed to suppress the remaining uncorrelated phase fluctuations between two optical frequencies by implementing optical-wavelength-scale action to vary the microwave phase. The actuator has been designed with the aid of a simulation that predicts actuation bandwidth and loss for a range of actuator parameters.

An Optical Link for the ACES and STE-QUEST Missions in Western Australia

Sascha Schediwy

Western Australia is becoming the premier southern hemisphere hub for high-precision ground-space timing missions. The University of Western Australia (UWA) is currently building a state-of-the-art optical atomic clock, and has been selected as the only southern hemisphere microwave-frequency ground station for the Atomic Clock Ensemble in Space (ACES) mission. We propose to construct a 60 km section of optical fibre to complete a link between UWA and the Yarragadee Satellite Laser Ranging facility and thereby enabling an optical link for the ACES and Space-Time Explorer and QUantum Equivalence Principle Space Test (STE-QUEST) missions.
