- Title: A prescriptive method for fibre polarisation compensation in two bases
- Authors: Teodor Str\"omberg and Peter Schiansky and Philip Walther
- Abstract summary: Single-mode optical fibres exhibit a small but non-negligible birefringence that induces random polarisation rotations during light propagation.
In classical interferometry these rotations give rise to polarisation-induced fading of the interferometric visibility.
In this Lab Note we review an efficient method for fully compensating fibre polarisation rotations for general input states.

- Abstract: Single-mode optical fibres exhibit a small but non-negligible birefringence
that induces random polarisation rotations during light propagation. In
classical interferometry these rotations give rise to polarisation-induced
fading of the interferometric visibility, and in fibre-based polarimetric
sensors as well as quantum optics experiments they scramble the information
encoded in the polarisation state. Correcting these undesired rotations is
consequently an important part of many experiments and applications employing
optical fibres. In this Lab Note we review an efficient method for fully
compensating fibre polarisation rotations for general input states. This method
was not originally devised by us, but does to the best of our knowledge not
appear in the literature, and our interactions with the community have
indicated that it is not well known.

We present a new scheme that allows for using polarization encoding in a fiber not only in the discrete, but also in the continuous-variable regime.
For the example of a helically twisted photonic-crystal fibre, we experimentally demonstrate that using appropriate nonorthogonal modes, the polarization-preserving fiber does not fully scramble these modes over the full Poincar'e sphere.
This will allow for more efficient measurements of quantum excitations in nonorthogonal modes.

We propose a method to optimize interference visibility by controlling polarizations to a crosspoint of two circular trajectories on the Poincar'e sphere.
Our method maximizes visibility with low optical loss, which is essential for quantum light, by using fiber stretchers as polarization controllers.
Our method makes fiber systems promising for practical fault-tolerant optical quantum computers.

We analyse the effect of a strong perpendicular magnetic field on an intersubband transition in a disordered doped quantum well strongly coupled to an optical cavity.
The magnetic field changes the lineshape of the intersubband optical transition due to the roughness of the interface of the quantum well from a Lorentzian to a Gaussian one.
