Abstract :
To decrease the switching length of the directional coupler switch and to use the advantages of the electro-optic properties of (LC´s), we propose a novel vertical Δκ directional coupler switch using LC´s and present the calculated results relevant to the design considerations. Because of the large birefringence of LC´s, a very short switching length less than 60 μm is possible. Besides, a N×N switch is also proposed for practical applications
