The device\'s function in an optical circuit is to emit and control light signals, which can then be transmitted through an optical fiber for further processing. It is important to understand the operation of this device and how it can be used effectively in an application.

Application Field

The DM200-01-1-9420-0-LC laser diode module is widely used in modern communication and industrial control systems. It is a suitable choice for many applications, such as optical networks, laser barcode scanners, RFID systems, production line monitoring, laser rangefinders, medical instrumentation, and other light-based components. As a diode laser, it provides a good output in terms of power and wavelength, which makes it well-suited for fiber optic communications.

Working Principle

The DM200-01-1-9420-0-LC operates by combining two different semiconductor materials into a single die, where one material acts as an emitter and the other as an absorber. An electrical input is supplied to the device, which triggers the emission of light in a narrow band of wavelength which exits the device through the surface or an optical fiber. The amount of light generated is determined by the magnitude of the current passing through the laser diode. The emitted light passes through a collimating lens, which ensures that the light is well-focused and collimated. The collimated light is then transmitted through an optical fiber or delivered straight to the target application.

In order to properly control and direct the light, the DM200-01-1-9420-0-LC utilizes specialized materials and fabrication processes. These processes ensure that light is emitted in a very narrow and focused spectral range, that is only influenced by the voltage across the diode. Additionally, the device is capable of producing a constant output power over a wide range of electrical input voltages.

The DM200-01-1-9420-0-LC is a compact device with minimal power consumption and is suitable for harsh environmental demands. It is an easy to integrate and relatively low cost solution for many laser diode applications, when compared to more complex laser diode systems.
