abstract = "Heterodyne laser phase measurements in the Laser Interferometer
Space Antenna (LISA) are degraded by the phase fluctuations of the
onboard clocks, resulting in unacceptable sensitivity performance
levels of the interferometric data. The current scheme for
cancellation of the clock phase noise requires 1 GHz modulation of
the ranging laser beams and additional interspacecraft clock
recovery heterodyne phase measurements. Here, we report
experimental results for an alternative approach to clock noise
cancellation based on modified second generation time-delay
interferometry (TDI) with optical frequency combs (OFCs). The use
of OFCs in the LISA scheme allows simultaneous cancellation of
both laser and clock noises, and would eliminate the need for 1
GHz laser modulations and associated demodulation detections. Two
Mach-Zehnder interferometers with acousto-optic modulators were
used to simulate two LISA arms with Doppler shifts and time
delays. With a self-referenced OFC locked to the laser providing
the clock signal, we achieve simultaneous suppression of laser and
clock noises by 7 and 1.5 orders of magnitudes, respectively, down
to the setup noise floor. Based on a numerical analysis, we
further show that the noise suppression performance of the
OFC-based TDI scheme can meet the LISA mission requirements with
an ample margin.",
