High-frequency combs have made possible some of the most advanced benchtop instrumentation available today (see for example, “Nonlinear VNA goes to 67 GHz,” edn ...

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 ...

Optical frequency combs have revolutionized technologies such as atomic clocks, spectroscopy, and ultra-fast lasers by acting as precise bridges between optical and microwave frequencies. As the ...

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 ...

A stable ‘frequency comb’ of photons with discrete colours has been generated on a microscale chip by removing copper contaminants from the circuit. The development of PICs was enabled by advances in ...

Chip-based optical frequency combs, or microcombs, have concurrently transformed the architecture of integrated photonics. These microcombs are indispensable for the co-integration of microwave and ...

Dual-comb spectroscopy is an innovative optical technique that exploits pairs of laser frequency combs—light sources whose spectra consist of equidistant narrow lines—to facilitate high-resolution, ...

Since the Nobel Prize in Physics was awarded in 2005 for the invention of optical frequency combs, they have become a core technology in information systems. An optical frequency comb consists of a ...
