Opto-Acoustic Oscillator Using Silicon Mems Optical Modulator
, 2011 We show operation of a silicon MEMS based narrow-band optical modulator with large modulation depth by improving the electro-mechanical transducer. We demonstrate an application of the narrowband optical modulator as both the filter and optical modulator

An optical modulator based on a single strongly coupled quantum dot - cavity system in a p-i-n junction [PDF]
, 2009 We demonstrate an optical modulator based on a single quantum dot strongly coupled to a photonic crystal cavity. A vertical p-i-n junction is used to tune the quantum dot and thereby modulate the cavity transmission, with a measured instrument-limited ...

Composite acousto-optical modulation
Optics Express, 2022 We propose a composite acousto-optical modulation (AOM) scheme for wide-band, efficient modulation of CW and pulsed lasers. We show that by adjusting the amplitudes and phases of weakly-driven daughter AOMs, diffraction beyond the Bragg condition can be achieved with exceptional efficiencies.

All-Optical In-Phase/Quadrature Microwave Mixer for Antenna Remoting Applications
IEEE Photonics Journal, 2021 A new microwave photonic signal processing structure for realising in-phase/quadrature (I/Q) mixing is presented. It is based on a dual-drive Mach Zehnder modulator (DDMZM) and an optical phase modulator inside a Sagnac loop interferometer.

All-Optical Modulation in a Silicon Waveguide Based on a Single-Photon Process [PDF]
, 2008 All-optical, low-power modulation is a major goal in photonics. Because of their high mode-field concentration and ease of manufacturing, nanoscale silicon waveguides offer an intriguing platform for photonics.

Superconducting acousto-optic phase modulator
Optics Express, 2021 We report the development of a superconducting acousto-optic phase modulator fabricated on a lithium niobate substrate. A titanium-diffused optical waveguide is placed in a surface acoustic wave resonator, where the electrodes for mirrors and an interdigitated transducer are made of a superconducting niobium titanium nitride thin film.
