| Abstract: | We have experimentally demonstrated a reconfigurable silicon
thermo-optical device able to tailor its intrinsic spectral optical response by
means of the thermo-optical control of individual and uncoupled resonant
modes of micro-ring resonators. Preliminarily results show that the device’s
optical response can be tailored to build up distinct and reconfigurable logic
levels for optical signal processing, as well as control of overall figures of
merit, such as free-spectral-range, extinction ratio and 3dB bandwidth. In
addition, the micro-heaters on top of the ring resonators are able to tune the
resonant wavelength with efficiency of 0.25 nm/mW within a range of up to
10 nm, as well as able to switch the resonant wavelength within fall and rise
time of 15 μs. |
