Parallel Resonance

Parallel Resonance

The parallel RLC circuit is an arrangement where the resistor (R), inductor (L), and capacitor (C) are all connected to the same nodes and, as a result, share the same voltage across them. The parallel RLC circuit is analyzed in terms of admittance (Y), which reflects the ease with which current can flow. The admittance is given by:

Propagation Speed of Electromagnetic Waves

Propagation Speed of Electromagnetic Waves

Electromagnetic waves are consistent with Ampere's law. Assuming there is no conduction current Ampere's law is given as:

Series Resonance

Series Resonance

The RLC circuit impedance is defined as the ratio of the supply voltage to the circuit current. Resonance in such a circuit occurs when the imaginary part of this impedance equals zero. This specific condition means that the inductive reactance is exactly equal to the capacitive reactance. The frequency at which this happens is known as the resonant frequency. Mathematically, the resonant frequency is inversely proportional to the square root of the product of the inductance (L) and capacitance...

Double Resonance Techniques: Overview

Double Resonance Techniques: Overview

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.
Spin decoupling is usually achieved by...

Area of Science:

Photonics and Optical Communications
Integrated Optics
Fiber Optic Sensing

Background:

Microresonator-based frequency combs are promising for wavelength-division multiplexing (WDM), potentially replacing multiple lasers with a single device.
Previous research demonstrated high throughput over short distances, but long-haul capabilities remained unproven.

Purpose of the Study:

To demonstrate the feasibility of long-haul coherent communication using a microresonator-based frequency comb source.
To assess the performance of integrated comb sources in extended fiber optic links.

Main Methods:

Modulating polarization multiplexed (PM) quadrature phase-shift keying (QPSK) data onto microresonator comb lines.
Transmitting data over more than 6300 km in a single-mode fiber.
Conducting a second experiment using PM 16 quadrature amplitude modulation (16-QAM) over 700 km.

Main Results:

Successful long-haul coherent communication demonstration exceeding 6300 km using a microresonator comb source.
Achieved transmission beyond 700 km with PM 16-QAM.
These results represent the longest fiber transmission achieved with an integrated comb source to date.

Conclusions:

Microresonator frequency combs are viable for long-haul WDM systems.
Integrated comb sources offer a scalable and efficient solution for future optical networks.
This work pushes the boundaries of integrated photonics for telecommunications.
