Abstract
An interleaver has a birefringent element assembly and a reflector configured so as to direct light from the birefringent element assembly back into and through birefringent element assembly. The birefringent element assembly has at least one birefringent element. Directing light from the birefringent element assembly back through the birefringent element assembly enhances transmission characteristics and/or mitigates dispersion.
Claims18
An interleaver comprising:
- a birefringent element assembly providing two output components;
- and
- a reflector configured to direct the two components from the birefringent element assembly back through the birefringent element assembly.
A method for interleaving, the method comprising:
- transmitting light through a birefringent element assembly, the birefringent element assembly separating the light into first and second generally orthogonal components;
- and
- transmitting the first and second components back through the birefringent element assembly.
A method for interleaving, the method comprising:
- transmitting light through a birefringent element assembly, the birefringent element assembly separating the light into first and second generally orthogonal components;
- and
- aligning the first and second components such that the polarization directions of the first and second components are approximately parallel with respect to one another.
