The capabilities of modal LC modulator (LC focusator) for optical vortices formation are demonstrated. Two options of changing of the contact electrodes geometry providing a voltage jump and accordingly the jump for profile of phase transmission of modulator are proposed. The examples of distributions of intensity and phase for generated fields are presented.
