SIMULTANEOUS TRANSFER OF MICROWAVE AND OPTICAL REFERENCE FREQUENCIES BY SELECTIVELY AMPLIFIED OPTICAL FREQUENCY COMB

摘要

A method for simultaneously transmitting optical frequency standard frequency and microwave reference frequency is provided to measure physical constant by using microwave reference frequency and optical frequency standard frequency having the high stability. A part of optical frequency is selected by a narrow interference filter from a phase stabilized femto second mode synchronized laser(2). The part of optical frequency selected by the narrow interference filter is amplified by using a semiconductor amplifier while maintaining a phase texture bond. The part of optical frequency selected by the narrow interference filter is transmitted through a fiber optic network.
