Triply resonant four-wave mixing in silicon-coupled resonator microring waveguides
Optics Letters
|November 1, 2014
Abstract:
Silicon photonic four-wave mixing (FWM) devices intended for telecommunications applications must satisfy three requirements: achieve conversion efficiencies close to the detection threshold of typical receivers, while keeping pump power requirements modest and providing enough bandwidth for typical signal formats. Here, we report a continuous-wave FWM efficiency of -21.3 dB at 100 mW pump power and demonstrate wavelength conversion at 10 Gbps in a coupled-resonator optical-waveguide device.

01:28Standing Waves in a Cavity
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:

01:12Double Resonance Techniques: Overview
856
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.
