Recent research has revealed a significant ability to manipulate and control a light beam to hide events in time-domain. Achieving highly functional temporal cloaking, which open up and subsequently close intensity gaps in the probe beam to conceal events from the observer with satisfied performances, are still difficult in optical fiber communication. Here, we propose and experimentally demonstrate...
In this talk, we review some progresses on tunable fractional photonic differentiator and first-order linear ordinary differential equation solver with an electronically tuned microring resonator.
We have demonstrated a chip-scale optical pulse shaper consisting of cascaded four-channel microdisk resonators. Different temporal waveforms can be generated through wavelength-to-time mapping at both through port and drop port with a thermal controller.
We demonstrate a multifunctional photonic differentiation (DIFF) using a phase modulator and two delay interferometers (DIs), including 1st order intensity DIFF, 1st order field DIFF and its inversion, 2nd order field DIFF.
