The 1550nm 40mW 200Khz Narrow Linewidth DFB Butterfly Laser Diode is based on a unique single DFB chip, adopts a unique chip design, advanced packaging technology, has low linewidth and relative intensity noise, and has low sensitivity to wavelength and working current. The device adopts standard 14 pin butterfly package, with high output power, high stability, high reliability.

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.

The 1350nm DFB Butterfly Laser Diode, with 120mW output through 900µm fiber pigtail. The fiber is approximately 1M in length, with FC/APC or FC/PC connector. The laser is excess-stock, new-in-box, and includes datasheet and test data.

Long Wavelength 2.0μm-band 1850~2000nm ASE Broadband Light Source is based on thulium fiber laser technology and with high output power.

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.

1368nm 10mW DFB Butterfly Laser is a cost effective, highly coherent laser diode, the DFB laser chip is packaged in an industry standard hermetically sealed 14 pin butterfly package with TEC and PD built in. It can be used for H2O gas detection.
