OUTLINE
Such a platform will benefit future high-capacity network systems, navigation, and other services. Since the dawn of history, mankind has elaborated technologies for timekeeping and developed applications to fully use time resources. These technologies have triggered a paradigm-shift in communication and information technologies. In order to facilitate a new breakthrough in industrial and academic fields introduced by highly-precise clocks, we will develop transportable and compact “optical lattice clocks” that allow remote maintenance and unattended operation.
By networking them via phase-stabilized fibers, we will demonstrate clocks’ application to relativistic geodesy and establish a space-time information platform that will substitute GNSS.
In this project, six groups participate in research and development.
・Optical Clock (OC) Group
Research and development of system for demonstration of optical lattice clock.
・Optoelectronics Module (OM) Group
Development of optoelectronic module for demonstration of optical lattice clock.
・Component (COM) Group
Development of optical components for demonstration of optical lattice clock.
・Network (NW) Group
Research and development of fiber networks for realizing optical lattice clock networks.
・Relativistic Geodesy (RG) Group
Research and Development of relativistic geodetic application technology using optical lattice clock.
・Re-definision of the Second (RS) Group
Promotion and development of redefinition of seconds using optical lattice clock.
・Social implementation research (SI) Group
Research and exploration of potential applications for the social implementation of optical lattice clock.
