The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a ...

Conventional EO polymer optical modulators could operate in near-infrared light (wavelength 1,550 nm, etc.), but they couldn't be used for visible light (wavelength 380 nm to 780 nm) because of ...

Using a phosphorus layer whose electro-optical wavelength can be shifted by mechanical stress opens new opportunities for test-and-measurement instruments. What black phosphorus is and how it can ...

When a high-precision wavelength meter and an OFC are used together, the optical frequency can be measured with an accuracy of 11 to 12 digits. Wavelength meters, on the other hand, require a ...

Electro-optic modulators, which control aspects of light in response to electrical signals, are essential for everything from sensing to metrology and telecommunications.

Now, for the first time in the world, we have demonstrated the transmission and reception of a digital coherent optical signal exceeding 2 Tbits/s per wavelength (Fig. 1, left) and successfully ...

NTT stabilized the frequency of an electro-optic modulation-based optical frequency comb for high-speed and large-capacity optical comms applications.
