(author)We report a highly sensitive ultrasound sensor based on an integrated photonics silicon Mach-Zehnder interferometer (MZI). One arm of the MZI is located on a thin membrane, acting as the sensing part of the device. Ultrasound waves excite the membrane's vibrational mode, thus inducing modulation of the MZI transmission. The measured sensor...conference paper 2020

Li, Ming Huang (author), Lu, Ruochen (author), Manzaneque Garcia, T. (author), Gong, Songbin (author)In this work, thin-film lithium niobate (LiNbO<sub>3</sub>) acoustic delay line (ADL) based oscillators are experimentally investigated for the first time for the application of single-mode oscillators and frequency comb generation. The design space for the ADL-based oscillator is first analyzed, illustrating that the key to low phase noise...conference paper 2020
