Electrooptic polarization switch for multimode fibers
Abstract:
An extensive theoretical analysis of an electrooptic polarization switch has been carried out. The main objective of the study is to ascertain whether it is possible to design such a switch with acceptable levels of optical crosstalk and control voltage if the device is used in conjunction with a multirmode optical fiber transmission system. The results of the study show that about 30-dB signal-to-crosstalk ratio can be obtained when an isotropic cubic material such as CdTe is used, and the fibers do not have an excessively large numerical aperture. Less isolation (~7 dB) can be obtained when using an anisotropic material with a small birefringence such as LiTaO(3). Drive voltages in either case range from 10 V to 50 V.
