HULD Laser Diode to Fiber Couplers

Receptacle Style; 375 to 2000 nm; Wavelength Accuracy ±5 to ±30 nm; Coupling Efficiency 10% to 75%; Fiber Type SM, MM or PM

OZ Optics’ HULD series of receptacle style laser diode to fiber couplers is offering optimum coupling in a small, rugged package. The couplers may be purchased prealigned, with the diode already in place, or as a kit that can be assembled by the customer using their own diode. The complete assembly procedure is quite straightforward. An assembly and operating instruction video on a USB drive, showing the alignment process, is available. In addition, a complete alignment kit is available, which includes the laser diode collimation wrench, multimode fiber assembly, centering lens, and video instructions.

Diode source couplers are available for a variety of diode case sizes, and for diode wavelengths from 375 nm to greater than 2000 nm. These source couplers work with MM, SM and PM fiber. HULD connector receptacle style couplers have a female receptacle, such as NTT-FC, or AT&T-ST, etc. at the output end. This allows the user to connect any optical fiber with a matching male connector to the diode. HULD laser diode to fiber couplers are available in different diameters from 0.79 inch to 1.3 inch. These tilt adjustable source couplers can be used over a temperature range of -25 °C to +60 °C and have been vibration tested. Higher temperature versions are available on request OZ Optics also offers special, low cost, miniature receptacle style laser diode to fiber couplers for OEM applications. These packages use just a single lens to couple light from the laser diode into the fiber. They do not use OZ Optics tilt adjustment technique. This package features a compact, rugged housing, at a lower cost.

A variety of options like a built-in isolator, a blocking screw to attenuate the output beam as well as polarizers or polarization rotators in the middle are also available.
