Characterisation of The Flow Of Light in Integrated Photonics Circuits Published in Nature Photonics

Next generation photonic chipThey have demonstrated the versatility of this all-optical modulation technique in imaging and in the quantitative characterisation of a range of properties of silicon photonic devices, from group indices in waveguides, to quality factors of a ring resonator, and to the mode structure of a multimode interference device. Ultrafast photomodulation spectroscopy provides important information on devices of complex design, and is easily applicable for testing at the device level. Press release
