Figure.1 Experimental setup. (a) Experimental setup for the robust single SMC formation. An auxiliary laser is introduced for the stable soliton formation. ECDL, External cavity diode laser; EDFA, ...

Like the teeth of a comb, a microcomb consists of a spectrum of evenly distributed light frequencies. Optical atomic clocks can be built by locking a microcomb tooth to a ultranarrow-linewidth laser, ...

A research team has successfully developed a self-locked Raman-electro-optic (REO) microcomb on a single lithium niobate chip. By synergistically harnessing the electro-optic (EO), Kerr, and Raman ...

Figure 1. Free-space terabit coherent optical communication based on Platicon microcomb. Figure 2. High power conversion efficiency Platicon microcomb. Figure 3. WDM polarization multiplexing Platicon ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...
