2009) Design of integrated 1×2, 1×4 low driving voltage polymer electro-optic switches based on Y-fed directional couplers, Journal of Modern Optics, 56:5, 615-622, Two integrated 1 Â 2 and 1 Â 4 polymer electro-optic switches based on Y-fed directional couplers are designed and optimized in terms of the coupled mode theory, electro-optic modulation theory, conformal transforming method and image method. The principle of the 1 Â 2 electro-optic switch is described. Parameters including the core size, buffer layer thickness, electrode thickness, electrode width and electrode gap are optimized. Simulation results show that the length of the designed 1 Â 2 switch is about 3.126 mm, the driving voltages of the two branches are as low as 0.891 and À0.891 V, respectively, the crosstalk and insertion loss are less than À30 and 1.42 dB, respectively, within the operation wavelength from 1527 to 1574 nm. Under the same driving voltages, the 1 Â 4 optical switch with a total length of less than 7 mm can be switched by altering the voltages applied on the electrodes of the three Y-fed directional couplers. Simulation results from the beam propagation method (BPM) indicate that the two designed devices exhibit favorable switching functions.
