Abstract

The transfer of ultra-stable optical frequencies through existing telecommunication fibre links is required to enable comparison of the most advanced optical clocks which are generally housed in National Metrology Institutes and typically separated by distances of a few 100 km to 1500 km. To meet the need for transparency in optical communication networks it is necessary to be able to shift the carrier wavelength between ITU-T channels in the C-band (1530 - 1565 nm). Here, we propose use of optical injection locking of a semiconductor laser to an optical comb to enable wavelength conversion in precision optical frequency transfer applications. The optical comb source used (from OptoComb Inc.) comprises a LiNbO3 phase modulator (PM) within a resonant cavity and generates a comb which spans the full C-band with a line spacing of 25 GHz.
