1550nm DFB Fiber Coupled Butterfly Laser Diode Manufacturers

The 850nm 7mW SLEDs SLDs for ophthalmic and medical OCT is a light source for ophthalmic and medical OCT application, fiber transmission systems, fiber optic gyros, fiber optic sensors,optical coherence tomography, optical measurements. The diode is packaged in 14-pin standard butterfly package with monitor photodiode and thermo-electric cooler (TEC). Module is pigtailed with single mode polarization maintaining fiber and connectorized by FC/APC connector.

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 1064nm 9W Multimode fiber pigtailed 2 PIN laser diode modules have a high efficiency, stability and superior beam quality. The modules are achieved by transforming the asymmetric radiation from the laser diode chip into an output fiber with small core diameter by using special micro optics. Inpection and burn-in procedures guarantee reliability, stability and long lifetime of each modules.

1570nm Coaxial DFB Laser Diode is fibre coupled with single mode optical fibre. CW output powers are wavelength dependent and lie between 2mW and 4mW. The distributed feedback cavity produces a linewidth of just 0.32nm, these laser diodes have a built in monitor photodiode and optical isolator. The SMF 28 optical output fibre can be terminated with SC/PC, FC/PC, SC/APC, or FC/APC connectors.
