Product Description:

OZ Optics offers a complete line of laser diode to fiber couplers, offering optimum coupling in a small,rugged package. They 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, and can be done in less than twenty minutes. A complete alignment kit, which includes tools and video instructions, is available separately.

Laser diode source couplers are available for a variety of diode case sizes, and for diode wavelengths from 400nm to greater than 2050nm. These source couplers work with multimode, singlemode, and polarization maintaining fiber. One advantage of the design is should the diode ever fail, it can easily be replaced while reusing the rest of the optics. The device can then be realigned for optimum coupling. There are two versions of tilt adjustable laser diode to fiber couplers - receptacle style couplers, and pigtail style couplers. Pigtail style laser diode to fiber couplers are offered with the fiber pigtailed directly onto the coupler. The pigtail style laser diode to fiber coupler provides higher coupling efficiencies and lower backreflection levels than receptacle style couplers, as well as better stability. The output fiber can be terminated with different output connectors, as desired.

Laser diode to fiber couplers are available in different diameters. The standard diameter package is 0.79" in diameter. This size fits almost all standard laser diode packages. The larger 1.3" diameter housing provides best coupling efficiencies as it permits a wider selection of coupling optics. This housing size is also used with large diode case sizes, such as TO-3 (H1) package sizes. A smaller 0.59" diameter housing is available for diode can sizes 9.0mm in diameter or smaller. For diodes with can diameters of 5.6mm or less, a miniature 0.5" diameter tilt adjustable housing is possible
