1576nm 10mW DFB Butterfly Laser Diode Manufacturers

A laser diode chip is a semiconductor-based laser that consists of a P-N structure and is powered by current. The laser diode package is a complete device that is assembled and packaged together in a sealed package housing to form a semiconductor laser chip that emits coherent light, a monitoring photodiode chip for feedback control of power output, a temperature sensor chip for temperature monitoring, or an optical lens for laser collimation.

We will be dedicated to provide customers with better quality products and faster response. And to help our customers create greater value and grow with customers.(China fiber optic modules)

Single-frequency lasers based on Er3+-doped or Er3+/Yb3+ co-doped gain fibers mainly work in the 1.5 μm band (C-band: 1530-1565 nm) and part of the L-band (1565-1625 nm). Its wavelength is in the C window of optical fiber communication, which makes the 1.5 μm band single-frequency fiber laser with narrow linewidth and low noise characteristics very important in coherent optical communication. It is used in high-resolution sensing, optical frequency domain reflectometer , laser radar and other fields also have a wide range of applications.

Optical fiber modules are components used to connect optical fiber cables to electronic devices. Optical fiber modules have many different parts, and different modules are designed to different specifications. Each part of the module is connected to a board that can be installed as a unit of electronic equipment.
