Abstract:
The orbital angular momentum (OAM) of light has promising applications, ranging from information multiplexing andhigh-speed optical communication to computation. Dynamically tunable and switchable vortex microlasers combinedwith direct photocurrent detection of the topological charges of OAM states have paved unexplored routes for thedevelopment and integration of fourth-generation (4.0) vortex technology, potentially on chip.

Clamper Circuit
Within this circuit, the diode's orientation prompts the capacitor to charge up to the level of the most negative peak of the input signal. Upon reaching this state, the diode ceases to...
Toroids
When connected to a supply, the magnetic field generated in the toroid has field lines circular and concentric to its axis. Conventionally, the direction of this magnetic field is expressed using the right-hand rule. If the fingers of the right hand curl in the current direction, the thumb points in...

The operation of a clipper circuit can be exemplified by analyzing a dual-clipper configuration setup that integrates two ideal diodes, each paired with a biasing...
Semiconductors
Metals such as copper (Cu), zinc (Zn), or lead (Pb) have low resistivity and feature conduction bands that are either not fully occupied or overlap with the valence band, making a bandgap non-existent. This allows electrons in the highest energy levels of the valence band to easily transition to the conduction band upon gaining...
