OZ Optics’ LPCA series of collimator/focuser array assemblies assist in developing next generation photonic devices. The arrays are manufactured using precision V-Groove technology in conjunction with single-element lens arrays, enabling sub-micron alignment accuracy.

OZ Optics fiber collimators and focusers are designed to collimate or focus light exiting a fiber to a desired beam diameter or spot size. By utilizing diffraction limited lenses, spot sizes of a few microns can be achieved. These devices can be used with photonic integrated circuits (PIC), arranged wave guides (AWG), and other fiber optic devices. Collimators and focusers can be used as matched pairs to couple light in and out of optical devices. This makes them ideal for dense fiber packaging devices.

OZ Optics’ LPCA precision fiber optic collimator/focuser array assemblies are available with single mode (SM) or polarization maintaining (PM) fibers. Customization can even include different types of fibers assembled into a single array. PM fibers offer a means to control the polarization of optical signals throughout the system thus minimizing polarization dependent losses (PDL) and polarization mode dispersion (PMD) effects. This control is crucial in developing next generation coherent detection systems. OZ Optics can also use customer supplied fibers to build devices.

Standard PANDA style PM arrays are manufactured with the polarization axis (stress rods) aligned vertical to the V-Groove base within 3°. High grade assemblies with one to eight channels can be provided with the stress rods aligned to 1°. Arrays can also be provided with the fibers aligned parallel to the base, alternating axes or at custom angles. When supplied with a breakout and connectors, the alignment of the connector is also to the slow axis, within 3° for standard connectors or available to within 1.5° for high grade connectors.

The LPCA collimator/foucser array assemblies can be manufactured with a hermetic feedthrough attached. This enables the development of multichannel photonic devices capable of meeting Telcordia requirements. Fiber breakouts can also be added, to convert ribbonized fibers into separated fibers, capable of being connectorized.
