The 1064nm Single Mode Fiber Coupled DFB Laser Diode utilizes a planar construction with chip on subcarrier. The high power chip is hermetically sealed in a epoxy-free and flux-free 14-pin butterfly package and fitted with a thermistor, thermoelectric cooler, and monitor diode. This 1064nm DFB laser diode provides a noise-free narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications that require the highest performance in spectrum control with the highest available powers.

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.

This 1350nm Coaxial DFB Pigtail laser diode has a built-in InGaAs monitor photodiode and an optical isolator integrated inside its package. This laser diode is suitable for applications in optical networks such as mobile communication systems and CATV systems.
