Pulsed Erbium-doped Fiber Amplifier Manufacturers

The 850nm 10mW TO CAN VCSEL Laser Diode is a standard Vertical Cavity Surface Emitting Lasers (VCSELs) in ready to use fiber coupled packages. it is in a small package TO56, Modulation and width >2GHz. We offer the 940nm 10mW VCSEL Laser Diode with multi-mode optical fiber 50um or 62.5um core optical fiber.

The 980nm 1030nm 1064nm high power fiber optical isolators is a fiber-coupled component that allows all polarized light signal (not just the light polarized in a specific direction) to propagate along a fiber in one direction but not in the opposite direction. Functionally, it is quite like an optic-electrical diode. The 980nm 1030nm 1064nm high power fiber optical isolators are necessary in fiber optic systems in many roles the most common of which is the prevention of back-reflected light coming back down a fiber from re-entering and disrupting the operations of a laser. Boxoptronics provide 1W,2W,3W,...,10W or other high power Polarization maintaining fiber isolators.

The 1550nm High Power Nanosecond Pulsed Fiber Laser uses a high-power gain fiber module and cooperates with a dedicated drive and temperature control circuit to output high-peak and high-energy laser pulses. The laser wavelength and power are stable, and the modular design is convenient for system integration. It can be used in laser radar, distributed optical fiber sensing systems, etc.

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 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.

This Low cost C-band ASE Broadband Light Source has C-band wavelength, with 5~7dB spectral flatness and SM fiber and for fiber sensing applications.
