unconventional light-matter interactions at the fingertip
Aiming to replace the electronic universal computing as its destiny, the integrated optics has gone a long way. Various kinds of materials, such as silicon, silicon nitride, silicon carbite, lithium niobate, aluminium nitride, etc., are extensively studied. Here we focus on these aspects in this field:
introducing novel optical phenomena and materials into integrated photonics
investigating the essential/critical prerequisites before (large-scale) photonic integration
introducing techniques in the state-of-the-art microelectronics into on-chip photonic integration
realizing theoretical works that have great potential yet overlooked.
An example of the 1st point: we introduced the novel temporal Talbot effect of dark pulse trains(Wu et al., 2022) into integrated optics (Wu et al., 2023).
The integrated chip with temporal Talbot effect.
One example of the 2nd point is the enhanced thermo-optic effects in epsilon-near-zero materials (Wu* et al., 2024), which are also CMOS-compatible (see near-zero-index nonlinear nanophotonics project). Introducing the state-of-the-art microelectronic technique can lead to unexpected interesting new findings, for instance, we applied the supercritical fluid technique to degenerate semiconductor photonic material for the first time (Wu et al., 2021). We also aim to employ our early theoretical works (see publications) into integrated nanodevices (nanostructure, thin-film device, metasurface), chips (hybrid & novel materials), and circuits (networks with certain topology) with our newly developed technique and in collaboration with our sister labs and colleagues around the world.
