Transformers

2.2K
A device that transforms voltages from one value to another using induction is called a transformer. A transformer consists of two separate coils, or windings, wrapped around the same soft iron core. However, they are electrically insulated from each other.
The iron core has a substantial relative permeability. Therefore, the magnetic field lines generated due to the current in one winding are almost entirely confined within the core, such that the same magnetic flux permeates each turn of both...

Transmission Electron Microscopy01:15

Transmission Electron Microscopy

7.7K
In 1931, physicist Ernst Ruska—building on the idea that magnetic fields can direct an electron beam just as lenses can direct a beam of light in an optical microscope—developed the first prototype of the electron microscope. This development led to the development of the field of electron microscopy. In the transmission electron microscope (TEM), electrons are produced by a hot tungsten element and accelerated by a potential difference in an electron gun, which gives them up to 400...

Types Of Transformers

1.7K
Transformers can provide desired voltages to a circuit by modifying the number of turns in the secondary windings.
If the ratio of the number of turns in the secondary winding to that of the primary winding is greater than one, then the transformer is said to be a step-up transformer. In a step-up transformer, the voltage at the secondary winding is greater than the voltage applied at the primary winding.
However, if this ratio is less than one, the transformer is said to be a step-down...

Dual Nature of Electromagnetic (EM) Radiation01:10

Dual Nature of Electromagnetic (EM) Radiation

4.6K
Electromagnetic (EM) radiation consists of electric and magnetic field components oscillating in planes perpendicular to each other and mutually perpendicular to radiation propagation through space. EM radiation can be classified as a wave, characterized by the properties of waves such as wavelength (denoted as λ) and frequency (represented by ν).
Wavelength is the distance between two consecutive peaks (the highest point) or troughs (the lowest point) in the wave. Frequency is the number of...

The Ideal Transformer01:26

The Ideal Transformer

1.5K
In single-phase two-winding transformers, two windings are coiled around a magnetic core characterized by cross-sectional area A and magnetic permeability μ. A phasor current i1 enters the left winding while i2 exits the right winding, establishing the fundamental working of the transformer through electromagnetic principles.
Ampere's Law forms the basis of understanding the magnetic field within the transformer. It states that the integral of the magnetic field intensity's tangential...

Plane Electromagnetic Waves I01:30

Plane Electromagnetic Waves I

5.3K
The existence of combined electric and magnetic fields that propagate through space as electromagnetic (EM) waves is the most significant prediction of Maxwell's equations. As Maxwell's equations hold in free space, the predicted electromagnetic waves do not require a medium for their propagation. An EM wave comprises an electric field, defined as the force per charge on a stationary charge, and a magnetic field, which is the force per charge on a moving charge.
The EM field is assumed to be a...

    Area of Science:

    • Optics and Photonics
    • Optical Communications
    • Quantum Information

    Background:

    • Orbital Angular Momentum (OAM) in light offers significant potential for increasing channel capacity in optical networks.
    • Higher-order Laguerre Gaussian modes carrying OAM are not directly compatible with standard fiber optic transmission, which favors the fundamental Gaussian mode.
    • A critical need exists for a method to interface OAM light with Gaussian mode time-binning for practical applications.

    Purpose of the Study:

    • To experimentally realize a photonic transcoder capable of converting between OAM light and Gaussian mode time-binning.
    • To demonstrate the bidirectional conversion of arbitrary OAM superpositions into time-bin Gaussian pulses and vice versa.
    • To validate the performance of the transcoder in terms of coherence conservation and mode crosstalk.

    Main Methods:

    • Development and experimental implementation of a novel photonic transcoder device.
    • Utilizing arbitrary OAM superpositions as input and time-bin Gaussian pulses as output, and vice versa.
    • Experimental verification of coherence preservation and absence of crosstalk between orthogonal modes.

    Main Results:

    • Successful experimental demonstration of a photonic transcoder for converting OAM light to time-bin Gaussian pulses and vice versa.
    • Confirmation that coherence is well-conserved throughout the conversion process.
    • Verification of no significant crosstalk between orthogonal optical modes.

    Conclusions:

    • The developed photonic transcoder provides a crucial interface between OAM multiplexing and standard fiber optic communication.
    • The device is simple, scalable, and maintains signal integrity (coherence and low crosstalk).
    • This technology paves the way for hybrid optical communication systems integrating free-space and fiber optic links.
