Paper Abstract

We demonstrate non-invasive light observation in silicon photonics with a ContactLess Integrated Photonics Probe (CLIPP), neither introducing appreciable perturbations of the optical field nor requiring photon tapping from the waveguide. Light monitoring with sensitivity down to -30 dBm, across 40 dB dynamic range, in few tens of microseconds, on TE and TM polarizations, and on monomode and multimode waveguides is achieved. Moreover, we show wavelength tuning, locking and swapping of high-Q resonators assisted by the CLIPP that is integrated inside the microring. CLIPP readout and feedback control is managed by a CMOS microelectronic circuit bridged to the silicon photonic chip.
