Summary

Photonics has come a long way in the last few decades and has now a profound impact on a wide range of fields and industries. Photonics is the study and application of generating, detecting, and manipulating light. The photonic device is the cornerstone of photonics and has a variety of uses. Originally focused on the telecommunications industry, photonics now has the potential to revolutionize various fields, including biology (photonic substrates), sensing (ultrasensitive sensors), energy production (high-efficiency solar cells), lighting (ultra-bright LEDs), and quantum technologies (single-photon sources, quantum information, quantum simulation).The combination of electron and photon confinement in modern photonic components has opened up new avenues for research and development, leading to the creation of novel devices and systems with improved performance. For example, the utilization of plasmons plays a significant role in shrinking the size of photonic devices. The enhancement of electric fields by plasmons allows for the creation of miniature optical components, such as nano-antennas, nanosources, sub-wavelength waveguides, and highly compact filters.
