840nm SLD diode Manufacturers

The 976nm 380Watt Fiber Coupled Diode Laser is an industrial standard laser diode in many welding applications, brazing, cladding, repair welding, hardening and other surface treatments. Also a commercial product for fiber laser pumping.

The 1550nm 10mW DFB Narrow Linewidth Laser Diodes series directly modulated external cavity laser is cost effective solution for 2.5Gbits/s digital transmission in SMF-28 fiber. This is fabricated in a hermetically sealed 14-pin butterfly package that contains thermoelectric cooler (TEC), thermistor, monitor photodiode, optical isolator. The NLD provides substantially lower dispersion penalty and lower chirp than a directly modulated DFB. The wavelength stability is assured by design, eliminating the need for wavelength lockers and complex feedback control circuits.

1550nm Superluminescent Diodes SLED are optical sources with a rather wide optical bandwidth. In that they differ from both lasers, that have a very narrow spectrum, and white light sources, that exhibit a much larger spectral width. This characteristic mainly reflects itself in a low temporal coherence of the source (which is the limited capability of the emitted light wave to maintain the phase over time). SLED may however exhibit a high degree of spatial coherence, meaning that they can be efficiently coupled into single-mode optical fibers. Some applications take advantage of the low temporal coherence of SLED sources to achieve high spatial resolution in imaging techniques. The coherence length is a quantity frequently used to characterize the temporal coherence of the light source. It is related to the path difference between the two arms of an optical interferometer over which the light wave is still capable to generate an interference pattern.

The 1550nm 10mW 10G DFB Electro-absorption Modulator Laser EAM EML laser diode integrated with DFB laser diode for 10G bit/s optical transmission, which are fabricated in a hermetically sealed butterfly package. Which built-in modulator, TEC, thermistor, monitor photodiode, optical isolator to secure high quality laser performance. We also have full customer selection of output powers, package types and output fibers of SM fibers. This module complies described in Telcordia GR-468-CORE requirement.

The 980nm ASE broadband light source based on the spontaneous emission of rare-earth optical fibers, offers high optical power and low polarization, covering the 980nm wavelength range. It is suitable for testing optical fiber loss and polarization, as well as for FBG grating production.

Boxoptronics' 1.5um Polarization Maintaining Passive Matching Fibers are matched with the erbium- ytterbium polarization-maintaining fiber. The high matching performance reduces the splicing loss and ensures the high-performance output of the polarization-maintaining erbium-ytterbium fiber in system applications.
