Oscillations In An LC Circuit

Oscillations In An LC Circuit

An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

Linear Approximation in Frequency Domain

Linear Approximation in Frequency Domain

Linear systems are characterized by two main properties: superposition and homogeneity. Superposition allows the response to multiple inputs to be the sum of the responses to each individual input. Homogeneity ensures that scaling an input by a scalar results in the response being scaled by the same scalar.
In contrast, nonlinear systems do not inherently possess these properties. However, for small deviations around an operating point, a nonlinear system can often be approximated as linear....

Standing Waves in a Cavity

Standing Waves in a Cavity

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:

Design Example: Underdamped Parallel RLC Circuit

Design Example: Underdamped Parallel RLC Circuit

Consider designing an oscillator circuit, a crucial component in various electronic devices and systems. The objective is to create an oscillator circuit with specific characteristics: a damped natural frequency of 4 kHz and a damping factor of 4 radians per second. To accomplish this, a parallel RLC circuit is employed, known for its ability to sustain oscillations at a resonant frequency. In this case, the damping factor is pivotal in achieving the desired performance.
Starting with a fixed...

RLC Circuit as a Damped Oscillator

RLC Circuit as a Damped Oscillator

An RLC circuit combines a resistor, inductor, and capacitor, connected in a series or parallel combination.
Consider a series RLC circuit. Here, the presence of resistance in the circuit leads to energy loss due to joule heating in the resistance. Therefore, the total electromagnetic energy in the circuit is no longer constant and decreases with time. Since the magnitude of charge, current, and potential difference continuously decreases, their oscillations are said to be damped. This is...

Background:

Fiber optical parametric oscillators (FOPOs) are crucial for generating tunable light sources.
Achieving large pump-signal separation in FOPOs is challenging due to nonlinear effects and stability issues.
Extended spectral separation is desirable for applications requiring distinct wavelengths.

Purpose of the Study:

To demonstrate a linear cavity fiber optical parametric oscillator (FOPO) with a significantly extended pump-signal separation.
To investigate the parametric conversion efficiency and signal-to-noise ratio at this large separation.
To assess the power stability of the generated signal and idler waves.

Main Methods:

Utilized a linear cavity fiber optical parametric oscillator configuration.
Employed a highly nonlinear fiber in the anomalous dispersion regime.
Generated a tunable idler wave by detuning the pump wavelength, achieving a 14.3 THz (116 nm) pump-signal separation.

Main Results:

Achieved a parametric conversion efficiency exceeding -35 dB despite the large pump-signal separation.
Recorded an average idler optical signal-to-noise ratio (OSNR) of 50 dB.
Demonstrated excellent power stability, with signal and idler peak power fluctuations below 1 dB over 30 minutes.

Conclusions:

Linear cavity FOPOs can achieve extended pump-signal separation while maintaining high efficiency and OSNR.
The demonstrated system offers a stable and efficient tunable light source for applications requiring large spectral gaps.
