1580nm DFB Butterfly Laser Diodes Manufacturers

Since the invention of the world's first semiconductor laser in 1962, the semiconductor laser has undergone tremendous changes, greatly promoting the development of other science and technology, and is considered to be one of the greatest human inventions in the twentieth century. In the past ten years, semiconductor lasers have developed more rapidly and have become the fastest growing laser technology in the world. The application range of semiconductor lasers covers the entire field of optoelectronics and has become the core technology of today's optoelectronics science. Due to the advantages of small size, simple structure, low input energy, long life, easy modulation and low price, semiconductor lasers are widely used in the field of optoelectronics and have been highly valued by countries all over the world.

Generally speaking, when people talk about infrared light sources, they are referring to light with vacuum wavelengths greater than ~700–800 nm (the upper limit of the visible wavelength range).

The basic components of a laser can be divided into three parts: a pump source (which provides energy to achieve population inversion in the working medium); a working medium (which has a suitable energy level structure that enables population inversion under the action of the pump, allowing electrons to transition from high energy levels to the lower level and release energy in the form of photons); and a resonant cavity.

Optical fiber array, using a V-groove (V-Groove) substrate, a bundle of optical fibers or an optical fiber ribbon is installed on the substrate at specified intervals to form an array.

Laser is considered to be one of the greatest inventions of mankind in the twentieth century, and its appearance has strongly promoted the progress of detection, communication, processing, display and other fields. Semiconductor lasers are a class of lasers that mature earlier and progress faster. They have the characteristics of small size, high efficiency, low cost, and long life, so they are widely used. In the early years, infrared lasers based on GaAsInP systems laid the cornerstone of the information revolution.
