Ultra-narrow Linewidth 3khz 1550nm Fiber Laser Module

The 1310nm DFB Butterfly Fiber Coupled Laser Diode is a high performance single wavelength source, available in a 14-pin butterfly package with PM fiber or SM fiber pigtail. The frequency response and linearity of this laser makes it an excellent choice for CATV systems, GSM/CDMA repeater, and optical sensing.

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.
