Structural phase transitions between layered Indium Selenide for inte-grated photonic memory
Tiantian Li, Yong Wang, Wei Li +10
The primary mechanism of optical memristive devices relies on the phase transitions between amorphous-crystalline states. The slow or energy hungry amorphous-crystalline transition…
Chiral exceptional point enhanced active tuning and nonreciprocity in micro-resonators
Hwaseob Lee, Lorry Chang, Ali Kecebas +6
Exceptional points (EPs) have been extensively explored in mechanical, acoustic, plasmonic, and photonic systems. However, little is known about the role of EPs in tailoring the dy…
Space Qualifying Silicon Photonic Modulators and Circuits
Dun Mao, Lorry Chang, Hwaseob Lee +7
Reducing the form factor while retaining the radiation hardness and performance matrix is the goal of avionics. While a compromise between a transistor s size and its radiation har…
Photocatalytic oxidation in few-layer Tellurene for loss-invariant integrated photonic resonance trimming
Dun Mao, Yixiu Wang, Hwaseob Lee +9
Two-dimensional materials with unique physicochemical properties promote photocatalytic activities. As the 2D material composites research studies the statistical average of comple…
Chiral exceptional point and coherent suppression of backscattering in silicon microring with low loss Mie scatterer
Hwaseob Lee, Ali Kecebas, Feifan Wang +3
Non-Hermitian systems with their spectral degeneracies known as exceptional points (EPs) have been explored for lasing, controlling light transport, and enhancing a sensor s respon…
Scalable photonic crystal waveguides with 2 dB component loss
Yahui Xiao, Feifan Wang, Dun Mao +5
Periodic or gradient subwavelength structures are basic configurations of photonic crystals and metamaterials. The measured linear losses of those nanophotonic devices are well-bey…
