Summary
This study explores using second-order nonlinearity as a single photon switch in coupled resonator waveguides, offering new control over single photon transmission and reflection.
Area of Science:
- Quantum optics
- Nonlinear optics
- Condensed matter physics
Background:
- Previous research on single photon scattering in 1D coupled resonator waveguides primarily used atom-based systems.
- A need exists for alternative mechanisms to control single photon behavior in these waveguides.
Purpose of the Study:
- To investigate the use of second-order nonlinearity as a single photon switch.
- To analyze single photon scattering properties by calculating transmission rates.
- To explore three-wave mixing for advanced single photon control.
Main Methods:
- Theoretical analysis of single photon scattering.
- Calculation of transmission rates within a 1D coupled resonator waveguide.
- Modeling of second-order nonlinear effects, including three-wave mixing.
Main Results:

32.7K
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...

622
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.

01:28Standing Waves in a Cavity
1.4K
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:
