Mode Multiplexers (LPMUX Series)

Space-Division Multiplexing has grown remarkably over the last few years. SDM typically involves using the different modes of few- or multi-mode optical fibres as unique data channels such that the capacity of the optical fibre can be scaled. One of the key challenges with this approach is finding a practical way of actually exciting and separating the fibre modes.

The mode multiplexers developed by Modular Photonics overcome this challenge with market-leading performance. They can be used for Research & Teaching in space-division multiplexing, fibre sensing and nonlinear optics.

The LPMUX series of multiplexers are based on integrated tapered mode couplers allowing for several standard single-mode inputs to be selectively converted into the individual LP modes of a few- or multi-mode fibre. The LPMUX series of mode multiplexers allow for low loss, high mode-selectivity and ultra-wideband performance beyond the telecommunications bands. The entry-level LPMUX3 multiplexer can be used for multiplexing or demultiplexing of the LP01, LP11a and LP11b modes.

Modular Photonics now also offers an LPMUX6 multiplexer capable of addressing 3-mode groups (LP01, LP11a, LP11b, LP02, LP21a and LP21b modes).

Modular Photonics products are assembled using industry standard alignment processes, allowing for reliable and low-loss connections for operation in telecomunications environments.

Note: Devices operating within custom wavelength ranges can also be ordered (between 600 -1700 nm).
