Summary
Nanoscale disorder causes bandwidth collapse in coupled photonic resonators. This study explores how the interresonator coupling coefficient affects this collapse, offering insights for device design.
Area of Science:
- Photonics
- Condensed Matter Physics
- Nanotechnology
Background:
- Coupled photonic oscillators and resonators are susceptible to nanoscale disorder.
- Disorder-induced localization in periodic structures can lead to bandwidth collapse.
- Bandwidth collapse is typically detrimental to photonic device performance.
Purpose of the Study:
- To investigate the relationship between interresonator coupling and bandwidth collapse in coupled photonic resonators.
- To determine how controlling the interresonator coupling coefficient impacts disorder-induced localization and bandwidth collapse.
Main Methods:
- Theoretical analysis of coupled photonic resonator systems.
- Numerical simulations to model disorder effects.
- Investigation of the role of the interresonator coupling coefficient.
Main Results:
- Bandwidth collapse is dependent on the interresonator coupling coefficient.
- The degree of coupling influences the severity and onset of localization.
- Controllable coupling offers a potential mechanism to mitigate bandwidth collapse.
Conclusions:
- The interresonator coupling coefficient is a critical parameter in managing bandwidth collapse in disordered photonic systems.
- Device design can be optimized by tuning coupling to counteract disorder effects.
- Findings provide a pathway for developing more robust photonic devices.
