Abstract

A multichannel fiber-optic delay-line architecture based on optical polarization switching is proposed that uses non-polarization-maintaining optical fibers. Critical birefringence-compensation and noise-reduction techniques are introduced and demonstrated for these delay lines, which show a high optical polarization extinction ratio (>39 dB) and a high electrical signal-to-noise ratio (>92 dB).

Experimental setups for the 1-bit optical delay line. The regular setup is for the noise-reduction scheme, whereas setup 2 with the Faraday rotator is for the birefringence-compensated design. In setup 2, LC3 simulates a fiber with variable birefringence noise induced by control of the driving voltage of the NLC device LC3. M1, M2, mirrors.
