A retarder stack for preconditioning at least partially polarized light for input to a modulator
includes a first retarder and the second retarder. The first retarder has a first retardance and …

A bias controller and a method for controlling the bias of an electro-optic modulator are
provided. In the method, for a received indication of modulator temperature, steps are …

A feed-forward predistortion circuit to provide improved linear response in optic modulators.
The circuit includes a non-linear element, an amplifier/delay means and a power combiner …

An external optical modulator is linearized to reduce second order distortion. An optical
carrier is modulated in the modulator by a pilot signal. The modulated optical carrier is …

(57) ABSTRACT A System architecture for a display System with electroni cally controlled
optical retarder Stacks. The System uses only one spatial light modulator and a color filter to …

A polarization insensitive electro-optic modulator is constructed by providing a polarization
beamsplitter to separate an incoming light beam into two orthogonally plane polarized …

A retarder stack for transforming at least partially polarized light includes a first retarder and
a second retarder. The first retarder has a first retardance and a first orientation and the …

SUMMARY OF THE INVENTION A wavelength Selective Switch is disclosed that includes
an optical System that is Symmetric about a polarization modulator and capable of …

An optical modulator is provided to control the intensity of a transmitted or re? ected light. In
a transmission mode, a separator splits arbitrarily polarized light into two polariza tion rays …

The present invention relates to an optical modulator that generates quaternary amplitude
modulated light without inter-symbol-interference by splitting input light into three optical …
