Optical characterisation techniques provide detailed insight into the amplitude, phase and dispersion properties of photonic components such as waveguides, modulators and detectors. Core methods ...

Metalens is a kind of optical metasurface composed of metaatoms for manipulating incoming light's amplitude, phase, and polarization. Unlike traditional refractive lenses, metalens can modulate the ...

The lithium niobate thin-film modulator was designed to achieve a modulation frequency of 350 kHz within the 0–2π phase range, further realizing high speed control of optical field coherence.
