What Is a Light Modulator?
A light modulator manipulates an optical signal to encode information, playing a crucial role in optical communication and sensing.
By adjusting light characteristics such as intensity, frequency, or phase, these devices embed data into light pulses. Such modulation enables the transmission of information through optical fibers or across free-space optical links.
While light modulators come in various types, their core function remains the same: to alter light properties for data transmission, sensing accuracy, or laser control. Key advantages of using light modulators include their ability to operate at high speeds, support extensive bandwidths, and be precisely controlled electronically. They are also known for their efficiency, compactness, and low energy consumption.
