Summary
We demonstrate controlling photon transport in a waveguide using an external mirror and a two-level atom. This method allows full modulation of resonant photon transmission and observation of Rabi splittings, even in weak coupling regimes.
Area of Science:
- Quantum optics
- Solid-state physics
- Photonics
Background:
- Controlling light propagation at the quantum level is crucial for quantum technologies.
- Cavity quantum electrodynamics provides a framework for light-matter interactions.
Purpose of the Study:
- To propose and theoretically investigate a method for controlling photon transport in a one-dimensional waveguide.
- To explore the influence of external mirror coupling on photonic transmission spectra and Rabi splittings.
Main Methods:
- A full quantum theory of photon transport in real space was employed.
- Numerical simulations were used to analyze transmission spectra and Fano resonances.
Main Results:
- Rabi splittings in photonic transmission spectra can be controlled by cavity-mirror couplings.
- Resonant photon transmission probability is fully tunable (0-100%).
- Fano resonance appearance is linked to coupling strengths and system dissipations.
Conclusions:
- The proposed system offers precise control over photon transport in waveguides.
- Rabi splittings are observable even in the weak coupling regime.
- Experimental realization using photonic crystal waveguides is feasible.

1.7K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...
