Photonics‐based microwave frequency mixing provides distinct features in terms of wide
frequency coverage, broad instantaneous bandwidth, small frequency‐dependent loss, and …

Electro-optic phase modulators are critical components in modern communication,
microwave photonic, and quantum photonic systems. Important for these applications is to …

In order to achieve small size, light weight, and immunity to electromagnetic interference, it is
desirable to replace bulky coaxial cables with optical fiber in advanced radar front-ends …

Coherent optical transponders are widely deployed in today's long haul and metro optical
networks using dense wavelength division multiplexing. To increase the data carrying …

We report our experimental results for linear analog optical links that use phase or frequency
modulation and optical discrimination. The discriminators are based on two architectures: a …

The first monolithically integrated optical phase-locked loop (OPLL) employing attenuating-
counter-propagating waves is presented. It demonstrates the highest dynamic range among …

We present a compact dual-arm thin-film lithium niobate (TFLN) electro-optic phase
modulator fabricated using the photolithography-assisted chemo-mechanical etching …

A novel ultracompact electro-optic phase modulator based on a single 9 μm-diameter III-V
microdisk resonator heterogeneously integrated on and coupled to a nanophotonic …

Frequency down-conversion is important to radar front-end. In this work, we achieve efficient
RF frequency down-conversion using a coupled quantum-well optical phase modulator …

The behavior of a sampling optical phase-locked loop (OPLL) is analyzed. An equivalent
time invariant system model for the sampling OPLL was derived. With the help of the model …
