A Fiber-Coupled AOM (Acousto-Optic Modulator) is a device that uses sound waves to control the intensity, frequency, and direction of light in an optical fiber. It's a versatile tool used in various applications, including laser systems, telecommunications, and scientific research.  

Key Components of a Fiber-Coupled AOM:

l Piezoelectric Transducer: Converts electrical signals into sound waves.

l Acousto-Optic Crystal: The medium through which the sound wave propagates and interacts with light.  

l Optical Fiber: Used to efficiently transmit the modulated light.

l RF Driver: Generates the RF signal to control the AOM's operation.  

By combining these elements, a fiber-coupled AOM offers precise control over light, making it a valuable tool in many optical applications.
