| Abstract | |
We report on experimental observations of a phenomenon whereby optical coupling of a high-power laser to a photonic subsystem locks a silicon microring's resonance if temperature of the photonic device is allowed to drift, causing the thermal tuning control to fail. This is the first report of such a failure mechanism, to our knowledge. We refer to this effect as ``optical hijacking{''} of the resonator wavelength. We demonstrate this effect showing that a ring resonator whose resonance drifts due to an increase in chip temperature can be locked to a normally nonresonant wavelength by injecting high optical power to the system leading to this ``optical hijacking{''} effect. Additionally, an analytical description of this effect is presented. (C) 2019 Society of Photo-Optical Instrumentation Engineers (SPIE) (AU) | |
