In the realm of optics, mirrors play a crucial role in manipulating light. But what if we could enhance their performance even further? Enter optical cavities, intricate structures that take mirrors to the next level.
Imagine a mirror facing another mirror. Between them, light becomes trapped and bounces back and forth, creating a standing wave pattern. This phenomenon is known as an optical cavity. The mirrors act as the boundaries for the light, confining it within their reflective embrace.
The beauty of optical cavities lies in their ability to amplify light. As light repeatedly bounces between the mirrors, it undergoes multiple constructive and destructive interference, resulting in a resonating effect. This amplifies certain wavelengths of light while suppressing others, creating a highly selective transmission or reflection profile.
Furthermore, the shape of the cavity plays a significant role. Concave mirrors bring light closer together, reducing the spacing between the standing waves and enhancing the amplification. Spherical cavities, on the other hand, create more evenly distributed standing waves.
