What is a Photonic Lantern?

Efficient, low-loss mode conversion between multimode and single-mode optical fibres.

How It Works

A photonic lantern consists of several single-mode fibres bundled together and gradually tapered into a single multimode core. Light entering the multimode end is adiabatically distributed across the single-mode outputs, while light entering the single-mode fibres combines into the multimode port.

This bidirectional capability makes photonic lanterns valuable for both mode multiplexing (combining signals) and mode demultiplexing (separating signals).

Low Insertion Loss

Adiabatic transition ensures minimal light loss during mode conversion.

Modal Completeness

Proper design ensures all spatial modes are captured and converted.

Compact Form Factor

All-fibre construction provides a robust, alignment-free solution.

Bidirectional Operation

Can be used for both multiplexing and demultiplexing applications.
