For the true time delay (TTD) of optical fiber changes with temperature, integrated optical chips are proposed to improve the delay consistency among channels. A 5-bit TTD chip is proposed in this paper. By using cascaded switches and optical wavegui

An approach is reported to acquire an optical frequency standard based on precise frequency locking between optical frequency comb and continuous wave. A stabilized erbium-fiber-based frequency comb is created by locking to the two-photon absorption

We demonstrate an approach of cold-atom frequency standard based on the two-photon transition (TPT) in rubidium (Rb), using an Erbium-fiber-based Frequency Comb. By introducing the technique of laser cooling and atoms trapping, our scheme can elimina

We propose to utilize an Er-doped fiber laser locked to a cooled Rb two-photon transition (TPT) resonance as a frequency standard for fiber-based optical communication. We show experimentally that a continuous wave laser beam can enhance the strength
