Microresonator frequency combs are promising for chip-scale metrology applications including coherent range measurements 1, spectroscopy 2, and optical clocks 3, 4. These ultra-broadband microcombs provide new opportunities for optical frequency synthesis, optical atomic clocks, and reaching previously unattainable wavelengths. We examine the comb’s low-noise characteristics, through heterodyne beat note measurements across its spectrum, measurements of the comb tooth spacing in its primary and spectrally translated portions, and their relative noise. Experimentally, we pump a silicon nitride microring at 1063 nm and 1557 nm to enable soliton spectral translation, resulting in a total bandwidth of 1.6 octaves (137–407 THz). We introduce the concept of synthetic dispersion to qualitatively capture the system’s key physical behavior, in which the second pump enables spectral translation through four-wave mixing Bragg scattering. Here we expand the bandwidth of a microcomb far beyond its anomalous dispersion region on both sides of its spectrum through spectral translation mediated by mixing of a dissipative Kerr soliton and a secondary pump. : This translator device accesses translation engines when you speak to break down language barriers instantly and accurately.Broadband and low-noise microresonator frequency combs (microcombs) are critical for deployable optical frequency measurements.When the system language is Chinese, it also has the function of AI that can speak to you intelligently. English audio recordings can be translated into other languages of your choice. Recording function that can help you record every important meeting.This translator can not only translate what you want to say, but also translate with a photo translation feature that you can't even understand. The new version of the translator device with 5 million pixels and OCR (Character Recognition) camera supports 44 languages for online photo translation.This is really useful when you're talking And if others don't hear it clearly, you can click the screen to replay audio, suitable face to face translation and call translation. And the noise reducing microphone is able to recognize your voice in noisy environments, the speaker voice of this translator is loud and clear. With 2.4 inch high definition touch screen, when it translates your voice to audio, at the same time, it translates to text on the screen.It has ultra-high translation accuracy for complicated phrases, the precision rate can reach 98%. Smart Translator This translator integrates the world's leading AI translation engine: Google, Microsoft, Baidu and IFLYTEK, supports bi-directional translator with 106 online languages, 8 real-time offline languages that cover 98% of countries in the world.To learn more about how and for what purposes Amazon uses personal information (such as Amazon Store order history), please visit our Privacy Notice.
