Superluminescent Diode SLDs Manufacturers

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.

1570nm DFB Butterfly Laser Diode Provide in a standard 14-pin butterfly mount, these laser diodes have a built in monitor photodiode, Peltier effect thermoelectric cooler, thermistor, and optical isolator. The SMF28 or PM fiber optical output fibre can be terminated with SC/PC, FC/PC, SC/APC, or FC/APC connectors.

The DWDM DFB Butterfly analog Laser Diode For CATV Application is a Dense Wavelength-Division Multiplexing (DWDM) laser for analog applications. It features a distributed feedback chip that has been designed specifically for Radio Frequency (RF) applications. The DWDM DFB Butterfly analog Laser Diode has a wide temperature range for reliable performance in harsh node environments and narrow transmitter designs. It also features low adiabatic chirp to maximize signal quality in short and long lengths of fiber. The laser’s excellent inherent linearity minimizes degradation of the broadcast signals caused by quadrature amplitude modulated (QAM) channels. The versatile DWDM DFB Butterfly analog Laser Diode reduces cable network architecture fiber needs and lessens equipment requirements in the hub.

The 940nm 12W LD COS Laser Chip on Submount, output power 12W, high efficiency, long lifetime, widely used in Industrial pump, R&D, Laser illumination, medical and other fields.

The 850nm Superluminescent Diodes SLD 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.

The 830nm 2W Fiber Coupled Diode Laser is designed to result in volume products with a high efficiency, stability and superior beam quality. The products are achieved by transforming the asymmetric radiation from the laser diode chip unto an output fiber with small core diameter by using special micro optics. Inspecting and burn-in procedures in every aspect come to a result to guarantee each product with the reliability, stability and long lifetime.
