High-speed tuning soliton microcomb: Method and device to tune comb lines and repetition rate of on-chip soliton microcomb at extremely fast speed.
­Background Spectrally pure microwaves are essential for many applications ranging from wireless communication to radar, clocks, and high-speed electronics. Soliton microcombs—phase-locked Kerr frequency combs produced on a monolithic chip—have recently come to light as a promising technique for synthesizing microwaves owing to their...

A new type of integrated semiconductor laser that achieves ultrafast tuning and switching
Background Frequency tuning of laser sources in Photonic integrated circuits (PIC) has been based on thermal as well as current changes. Thermal-optic tuning is slow (kHz) and current sweep techniques lead to unwanted intensity modulation. PICs still lack ultra-fast frequency modulation and switching, an essential attribute for the wide adoption of...

Titanium oxide coatings drastically reduce thermal effects in Lithium Niobate
ProblemLithium niobate (LN), possessing wide transparent window, strong electro-optics effect and large second/third- order nonlinearities, is an ideal material platform for integrated photonic applications. Microring resonators are particularly suitable as integrated photonic components, given their flexibility of device engineering and their potential...

Optomechanical Disk Vibratory Gyroscopes
Patent AbstractAn integrated optomechanical disk vibratory gyroscope device includes a mechanical oscillator having a substantially circular structure. The substantially circular structure is supported by a pillar, and mechanically isolated from a surrounding structure by a gap or slot. One or more actuators are coupled to the mechanical oscillator...

A Microchip Optomechanical Accelerometer
Patent AbstractTechnologies are generally described for operating and manufacturing optomechanical accelerometers. In some examples, an optomechanical accelerometer device is described that uses a cavity resonant displacement sensor based on a zipper photonic crystal nano-cavity to measure the displacement of an integrated test mass generated by acceleration...
