Abstract Resonator-based optical frequency comb generation is an enabling technology for a myriad of applications ranging from communications to precision spectroscopy. These combs can be generated in nonlinear resonators driven using either continuous-wave (CW) light, which requires alignment the pump with cavity resonance, or pulsed also mandates that pulse repetition rate and free spectral range (FSR) are carefully matched. Advancements nanophotonics have ignited interest chip-scale combs. However, realizing pulse-driven on-chip Kerr remains challenging, as microresonator cavities limited tuning their FSR resonance frequency. Here, we take steps overcome this limitation demonstrate broadband χ (3) resonator synchronously pumped by tunable femtosecond generator amplitude phase modulators. Notably, employing pumping overcomes limitations typically seen crystalline stimulated Raman scattering.

Single-frequency ultranarrow linewidth on-chip microlasers with a fast wavelength tunability play game-changing role in broad spectrum of applications ranging from coherent communication, light detection and ranging, to metrology sensing. Design fabrication such sources remain challenge due the difficulties making laser cavity that has an ultrahigh optical quality (Q) factor supports only single lasing frequency simultaneously. Here, we demonstrate unique single-frequency mechanism on erbium ion-doped lithium niobate (LN) microdisk through simultaneous excitation high-Q polygon modes at both pump wavelengths. As are sparse within gain bandwidth compared whispering gallery mode counterpart, while their Q factors (above 10 million) even higher significantly reduced scattering propagation paths, as narrow 322 Hz is observed. The measured three orders magnitude narrower than previous record LN microlasers. Finally, enabled by strong linear electro-optic effect LN, real-time electro-optical tuning microlaser high efficiency ∼50 pm / 100 V demonstrated.

Here, we demonstrate compact pure silicon modulator that shatters present 110 gigahertz. The proposed is built cascade corrugated waveguide architecture, which gives rise slow-light effect. By comprehensively balancing series merits, can benefit from slow light better efficiency size while remaining sufficiently high bandwidth. Consequently, realize 110-gigahertz with 124-micrometer length, enabling 112 gigabits per second on-off keying operation.
