We present our detailed study of a micromachined substrate approach for a wide-band lithium-niobate modulator and other ultra-wideband RF interconnection applications. Resonant substrate mode coupling often results in large RF loss that affects the frequency performance in LiNbO/sub 3/ modulators. Using the micromachining approach, we demonstrated… (More)
An integrated photonic microwave mixer, implemented with cascaded balanced bridge Mach-Zehnder modulators, is presented. The input and local oscillator frequency components are effectively rejected at the output, as demonstrated using a lithium niobate device.
