LUNA POS-203 – Polarisation Stabiliser, 3 Port
- Reset free operation
- External feedback ports
- Tunable operation parameters
- Low insertion loss
The LUNA POS-202, POS-203 and POS-204 polarisation stabilisers maintain stable output states of polarisation (SOP) against rapid input SOP fluctuations, compensating for an input polarisation discontinuity in as fast as 5 ms, or tracking without resets against a continuous input SOP rotation of up to 32π/s. The POS-20X architecture includes a polarisation controller, in-line polarisation monitor, and proprietary algorithms.
The POS-203 has optical ports for signal input and output and a third port for an optical feedback signal. It automatically optimises the output SOP to either maximise or minimise and optical or electrical feedback signal. It also allows the operator to control the step size, feedback delay, activation threshold, and search algorithm (maximum or minimum) from the front panel as well as remotely via one of the digital interfaces.
APPLICATIONS
- Eliminate polarisation fluctuations in fibre systems
- Suppress noise figure in optical amplifiers
- Reduce PDL effects
- Demultiplex polarisation division multiplexed channels
- Stabilise output SOP of high power laser amplifiers
