Abstract Bandwidth and noise are fundamental considerations in all communication and signal processing systems. The group-velocity dispersion of optical fibers creates nulls in their frequency response, limiting the bandwidth and hence the temporal r

We integrate a bow-tie antenna on a thin-film lithium niobate (TFLN) phase modulator to form an electromagnetic E-field sensor. The fiber-coupled TFLN chip is probed by a two-tone optical local oscillator generated using an external phase modulator,

High‐speed modulators with low driving voltage, low loss, and compact size are essential for future optical communication systems. Thin‐film lithium niobate modulators have met each of these criteria separately, but simultaneous achievement of al

Herein, frequency conversion to the third‐ and fourth‐order harmonics are demonstrated in ultracompact cascaded periodically poled thin‐film lithium niobate (LN) waveguides on silicon substrates. Pumped at 1550 nm wavelength, the tightly confin

The cascaded integration of optical waveguides with third-order optical nonlinearity ( $\chi ^{(3)}$ susceptibilitiy) with lithium niobate (LiNbO $_{3}$) waveguides is demonstrated on the same chip. Thin-film (LiNbO$_{3}$) and chalcogenide (ChG) glas

A synchronously pumped Kerr cavity is proposed and studied for power-efficient frequency comb generation in optical microring resonators. The system is modeled using the Lugiato-Lefever equation. Analytical solutions are provided for an ideal case an
