Zusammenfassung: | A method of fabricating active liquid crystal (LC) devices incorporating
liquid crystal polymer (LCP) films with passivation layers in combination
with conventional LC monomers is presented. Unlike monomeric LC
waveplates, LCP waveplate stacks can be produced on a single substrate.
Furthermore, the passivation layer is shown to act as an effective
alignment and protective layer for LC monomers and LCPs, thus enabling the
assembly of variable LC components with integrated thin film LCP waveplates
in an LC cell configuration. Such active devices with thin film waveplate
stacks are useful in applications such as tunable wavelength filters for
wavelength division multiplexing (WDM) communication systems. The device
fabrication method is used to produce a single-unit, double-pass,
polarization-insensitive variable LC phase modulator (LCPM). |
