Abstract:
A phase modulation device is provided that comprises a retardation device and a control device. The retardation device is characterized by first and second polarization eigenstates SOP f  and SOP s . Light polarized according to the second polarization eigenstate SOP s  acquires, upon passing through said retardation device, a delay with regard to light polarized according to the first polarization eigenstate SOP f , which delay corresponds to λ/2±30%, preferably λ/2±20% and most preferably λ/2±10%. The retardation device is arranged to receive input light having a polarization state SOP f ; that defines an angle with respect to one of the first and second polarization eigenstates SOP f , SOP s  within a predetermined angle range and to emit output light. The control device is configured to control at least one of a change of the angle between the polarization state SOP i ; of the input light and the respective polarization eigenstate SOP f , SOP s  by less than 0.1*π, preferably less than 0.05*π and most preferably less than 0.02*π; and a change of the amount of said delay upon passing through said retardation device by less than 0.3*λ, preferably less than 0.2*λ and most preferably less than 0.1*λ, such that a phase shift of π±30%, preferably π±20% and most preferably π±10% on the output light is obtained.

Claim (Index 2):
The phase modulation device of  claim 1 , wherein\n said control device is configured to receive a data signal or a modulation signal and to control at least one of said change of the angle and said change of the amount of delay according to said data signal or control signal.
