Decoding the control mechanism of spatial mode interactions
Exploration of spatial mode interactions in bent structures is a cutting-edge research area in integrated silicon photonics. The focus of this research is the control and operation of phase modulators (PMs). This includes understanding the unique concept of reciprocal points and how their strategic placement can effectively control the switching state of the PM.
An important advance in this field is the design and fabrication of reconfigurable microring resonators (rMRRs). This innovative device enables ultra-wideband and high-resolution microwave and millimeter wave applications and promises a significant advance in the development of 6G wireless communications technology.
Furthermore, dynamic control of PM is achieved through thermo-optic effects, opening new prospects for ultra-broadband operation.
Revealing the versatility of photonic molecular switches in multimode microcavities
A recent article delves into the potential of versatile photonic molecular switches in multimode microcavities. This introduces a flexible tuning methodology for dynamic control of spatial modes and interaction strength in multimode microrings. This control allows transitions between single-mode and multi-mode states, providing a wider range of applications.
An interesting interaction between the optical modes leads to the formation of hybridized supermodes and the appearance of spectral splitting. This phenomenon is often referred to as photonic molecules. To realize these photonic molecules, we investigate the control mechanism of spatial mode interactions in widened multimode racetrack MRR.
Furthermore, this study demonstrates a casting-based silicon microring with high Q-value and high free spectral range. It successfully verified an ultra-wideband tunable integrated millimeter-wave photonic filter and an integrated optoelectronic oscillator.
Insights from nanophotonics
Nanophotonics is a rapidly evolving field focused on the interaction of photons and nanostructures. It has been the hotbed of many recent international research results, specific developments, and new applications. This research is particularly relevant to physicists, engineers, and materials scientists working on new-age technologies such as 6G wireless communications.
Nanoarchitectonics and confined spaces
The review paper discusses nanoarchitectonics of confined spaces, focusing on the control of functional materials and molecular machines at the nanometer level. In this paper, we introduce dynamic capabilities in confined spaces and investigate the behavior of molecular machines, such as molecular motors, in these spaces.
This paper emphasizes that both the central functional unit and the surrounding spatial configuration are important for developing higher-level functions. This understanding is crucial for deciphering spatial mode interactions in bent structures and controlling PM to improve the performance of 6G wireless communication technologies.
