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 ...

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 ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

It may seem at times that there is a divide between the optical/photonic domain and the RF one, with the terahertz zone between them as a demarcation. If you need to make a transition between the ...

The rapid evolution of integrated photonics is driving the demand for multifunctional material platforms that support diverse on-chip optical operations. Among these platforms, thin-film lithium ...
