We demonstrate non-reciprocal continuous-wave transmission through integrated Si3N4 and LiNbO3 micro-resonators using the Kerr nonlinearity. We achieve a 5 dB non-reciprocal transmission ratio with 30 mW input power on Si3N4, a significant step towar

Many attractive photonics platforms still lack integrated photodetectors due to inherent material incompatibilities and lack of process scalability, preventing their widespread deployment. Here, we address the problem of scalably integrating photodet

Integrated circulators and isolators are important for developing on-chip optical technologies, such as laser cavities, communication systems, and quantum information processors. These devices appear to inherently require mirror symmetry breaking to

Integrated photonics operating at visible-near-infrared (VNIR) wavelengths offer scalable platforms for advancing optical systems for addressing atomic clocks, sensors, and quantum computers. The complexity of free-space control optics causes limited

Photonic modal circulator using temporal refractive-index modulation with spatial inversion symmetry
It has been demonstrated that dynamic refractive index modulation, which breaks time-reversal symmetry, can be used to create on-chip non-reciprocal photonic devices. In order to achieve amplitude non-reciprocity, all such devices moreover require mo

We show that a modal circulator can be achieved in a dynamically-modulated structure that preserves mirror symmetry. Such circulators can be implemented using only a single standing-wave modulator, which greatly simplifies the design of on-chip nonre
