The laser diode to fiber couplers from OZ Optics come in a compact and rugged package, offering optimal coupling efficiency. They can be purchased prealigned, with the diode already installed, or as a kit for customer assembly using their own diode. The assembly process is straightforward and can be completed in less than twenty minutes. A complete alignment kit, including tools and video instructions, is available separately.

These couplers are designed to work with various diode case sizes and wavelengths ranging from 400nm to over 2050nm. They are compatible with multimode, single mode, and polarization maintaining fibers. One advantage of the design is that if the diode fails, it can be easily replaced while reusing the rest of the optics, and the device can be realigned for optimal coupling.

There are two versions of tilt-adjustable laser diode to fiber couplers: receptacle style and pigtail style. The pigtail style couplers have the fiber pigtailed directly onto the coupler, providing higher coupling efficiencies, lower backreflection levels, and better stability. The output fiber can be terminated with different connectors as desired.

The couplers are available in different diameters, including standard 0.79" and larger 1.3" packages for improved coupling efficiencies and compatibility with larger diode case sizes. Smaller diameter options are also available for specific diode can sizes.

Optional features include couplers with built-in isolators to reduce backreflection effects, blocking screws to attenuate the output beam for precise power control, and couplers with polarizers or polarization rotators in the middle.

The product is offered with different part numbers and specifications, including wavelength, coupling efficiency, fiber type, and connector options. The specifications and ordering information for standard parts and custom parts are provided in the description.
