Miniaturized chaos-assisted Spectrometer | Light: Science & Applications
Principle
The chaotic spectrum is based on an individual asymmetric microdisk resonator, which undergoes a smooth deformation of the boundary. The boundary curve of the cavity is described by the Limaçon of Pascal, which is expressed in polar…

On-chip topological edge state cavities
Design of TESCs
We start with a topological waveguide design featuring a straight zigzag interface (Fig. 2a). The silicon VPC slab has a lattice constant a = 220 μm and a thickness of 190 μm. The unit cell consists of two equilateral…

Dynamic holographic display with addressable on-chip metasurface network based on lithium niobate photonics
Concept of addressable on-chip metasurface network
As the conceptual diagram shows in Fig. 1, the proposed addressable OCMN could be understood as three procedures, namely grating coupling, optical routing and guided wave radiation. To be…
