Abstract
The development of phase-stabilized ultrafast lasers has made possible
recent advances in optical atomic clocks exhibiting excellent short-term stability
that exceeds that of existing atomic clocks based on microwave transitions. The high
stability these systems possess has created a need for remote frequency transfer
capable of preserving this stability, which has applications ranging from
telecommunications to studies of fundamental physics.
Following an introduction of the use of ultrafast lasers in the implementation of
optical atomic clocks and for optical frequency metrology, I will discuss their
application to the remote transfer of frequency standards over optical fibers. The
transfer of both optical and radio-frequency references will be discussed, as well as,
the active cancellation of fiber-induced noise to reduce the instability
introduced during transfer over several kilometers.
