Abstract
There is provided an optical diode comprising a circular polarisation splitter, a first circular polariser and a second circular polariser. The circular polarisation splitter is arranged to receive at least partially unpolarised light and output right-handed circular polarised light along a first optical path and left-handed circular polarised light along a second optical path. The first circular polariser is arranged on the first optical path and transmits right-handed circular polarised light and reflects left-handed circular polarised light. The second circular polariser is arranged on the second optical path and transmits left-handed circular polarised light and reflects right-handed circular polarised light.
Claims28
An optical diode comprising:
- a circular polarisation splitter arranged to receive at least partially unpolarised light and output right-handed circular polarised light along a first optical path and left-handed circular polarised light along a second optical path;
- a first circular polariser arranged on the first optical path, wherein the first polariser is arranged to transmit right-handed circular polarised light and reflect left-handed circular polarised light;
- and
- a second circular polariser arranged on the second optical path, wherein the second polariser is arranged to transmit left-handed circular polarised light and reflect right-handed circular polarised light.
An optical diode as claimed 18 wherein the molecules are rotated about a propagation axis of incident light.
