In-Line Multimode Fiber Speckle Homogenizer

1 to 48 Channels; Channel Spacing 250 µm; Fiber Type SM, MM, PM; Connector Type SC, FC, ST, LC, MU; Insertion Loss <0.5 dB per Fiber OZ Optics’ VGA series of V-Groove array assemblies assists in developing next generation photonic devices. The arrays are manufactured using precision silicon wafer V-Groove technology or Pyrex V-Groove in conjunction with a Pyrex lid, enabling sub-micron alignment accuracy with UV cure attachment capabilities. VGA series V-Groove array assemblies are available with single mode (SM), multi mode (MM) or PANDAtype polarization maintaining (PM) fibers. Customization can even include different types of fibers assembled into a single array. In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber structure when building polarization maintaining components and patch cords. However OZ Optics can construct devices using other PM fiber structures. OZ Optics also carries some alternative fiber types in stock, please contact AMS Technologies for availability. If necessary, OZ Optics is willing to 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. V-Groove 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.

Neutral Density Filter, Pigtail Style; Fiber Type SM, MM, PM; 800 to 1625 nm; Connector Type NTT-FC/PC, ST, SC, LC/PC, other; Attenuation IL to 40 dB OZ Optics’ BB-500-11-ND series of compact PC board mountable, pigtail style variable attenuators are designed to meet Telcordia requirements. These attenuators with low backreflection can be used for 1300 nm and 1550 nm, as well as for C, L and S bands, with minimal changes in the insertion loss. Mounting holes provide easy attachment to PC boards and patch panels. The mounting hole patterns and attenuator sizes can be modified to meet customer requirements.The attenuators consist of two baseplates, each baseplate containing a fiber followed by a collimating lens. The attenuator is prealigned for optimum coupling efficiency using a patented tilt alignment technique. A variable neutral density filter is used to provide more uniform attenuation in multi mode applications than the blocking screw technique. The attenuation is controlled by a turn screw on the side of the attenuator, which controls the position of the filter. Variable attenuators based on the neutral density filter are ideal for multi mode fiber applications where one may be concerned about modal noise. When blocking style attenuators are used with multi mode fiber, some modes are blocked, while others are transmitted. This can produce 1 dB or greater modal noise fluctuations with coherent sources. A variable attenuator using a neutral density filter is not as strongly affected by modal noise. However, neutral density filter attenuators offer lower attenuation range (around 40dB) and can only handle about 50mW of power. While generally used for multi mode applications, OZ Optics can also produce single mode and polarization maintaining versions.
