Y-branch optical modulator. Jaeger, Nicolas A. F.; Lai, Winnie C.
Abstract
To characterize z-cut Ti:lithium niobate Y-branch optical modulators, numerical simulations are performed showing that high on/off ratios are attainable without special Y-junction asymmetries or long electrodes. The effective index and 2-D finite difference beam propagation methods were used for the simulations. A modulator with a 2 deg. Y-branch was fabricated. The measured on/off ratios were 5:1 at 25 V, 12:1 at 50 V, and 60:1 at 75 V, corresponding to 4:1, 12:1, and 62:1 for the simulations for a wavelength of 632.8 nm.
