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 DFB Coaxial Laser Diode Built-in TEC is generally applied for stabilizing or modulating light source. In addition, the high stability laser source can be used for testing apparatus and OTDR equipment. The laser diode is composed of a CWDM-DFB chip, built-in isolator, built-in monitor photodiode and TEC cooler, and SC/APC,SC/PC, FC/APC,FC/PC optical fiber connector. The laser diode devices are packaged in a compact hermetic assembly together with monitor photodiode and isolator for flexible integration into various transmitter configurations, Customers can select the length of optical fiber and pin definition based on actual demand. The output power is available from 1MW, 1270nm~1610nm CWDM wavelength available.

The 1430nm Coaxail Pigtail Laser Diode has a built-in InGaAs monitor photodiode and an optical isolator integrated inside its package. Output power from fiber >2mW, This laser diode is suitable for applications in optical networks such as mobile communication systems and CATV systems.

50um InGaAs Avalanche Photodiode Chip is photodiode with internal gain produced by the application of a reverse voltage. They have a higher signal-to-noise ratio (SNR) than photodiodes, as well as fast time response, low dark current, and high sensitivity. Spectral response range is typically within 900 - 1650nm.
