Microcavities, also known as optical resonators, are fascinating structures that confine and enhance light within a small volume. These tiny cavities, typically ranging in size from a few hundred nanometers to a few micrometers, have revolutionized the field of optics and photonics, paving the way for groundbreaking advances in various technological domains.

The Microcavities Series on Semiconductor Science and Technology Volume 16 delves into the intricate world of microcavities, providing a comprehensive overview of their principles, applications, and cutting-edge research. This book serves as an invaluable resource for researchers, students, and professionals seeking to understand and harness the remarkable capabilities of microcavities.

Principles and Types of Microcavities

Microcavities operate on the fundamental principles of light confinement and resonance. By confining light within a small volume, microcavities can significantly enhance its interactions with matter, leading to a wide range of optical phenomena.

Various types of microcavities exist, each with unique properties and applications. Some of the most common types include:

Planar microcavities: These consist of thin layers of alternating materials with different refractive indices, creating a high-finesse optical cavity.
Whispering-gallery mode microcavities: These utilize the principle of total internal reflection to confine light within a curved structure.
Photonic crystal microcavities: These employ periodic arrangements of dielectric materials to create photonic bandgaps, resulting in highly efficient light confinement.
Surface plasmon microcavities: These exploit the interaction between light and surface plasmons, enabling subwavelength light confinement and enhanced optical interactions.

Applications of Microcavities

The applications of microcavities are vast and encompass a diverse range of fields, including:

Lasers: Microcavities play a crucial role in the development of compact, high-power, and wavelength-tunable lasers.
