“…This approach is not scalable due to the large footprint and increased insertion losses when daisy-chaining. In the past decade, significant effort has been devoted to integrated microwave photonics [494,495]. However, existing material platforms, namely SOI, SiN x and InP, are facing particular challenges, especially in realizing high-performance EO components.…”

Lithium niobate (LN), an outstanding and versatile material, has influenced our daily life for decades: from enabling high-speed optical communications that form the backbone of the Internet to realizing radio-frequency filtering used in our cell phones. This half-century-old material is currently embracing a revolution in thin-film LN integrated photonics. The success of manufacturing wafer-scale, high-quality, thin films of LN on insulator (LNOI), accompanied with breakthroughs in nanofabrication techniques, have made high-performance integrated nanophotonic components possible. With rapid development in the past few years, some of these thin-film LN devices, such as optical modulators and nonlinear wavelength converters, have already outperformed their legacy counterparts realized in bulk LN crystals. Furthermore, the nanophotonic integration enabled ultra-low-loss resonators in LN, which unlocked many novel applications such as optical frequency combs and quantum transducers. In this Review, we cover-from basic principles to the state of the art-the diverse aspects of integrated thinfilm LN photonics, including the materials, basic passive components, and various active devices based on electro-optics, all-optical nonlinearities, and acousto-optics. We also identify challenges that this platform is currently facing and point out future opportunities. The field of integrated LNOI photonics is advancing rapidly and poised to make critical impacts on a broad range of applications in communication, signal processing, and quantum information.

“…[ 1 ] SBS has been widely investigated in bulk media [ 2,3 ] and optical fibers, [ 4–6 ] and has underpinned a wide range of important applications, based on the unique nature of high‐efficiency parametric (de)amplification and the ultra‐fine spectral selectivity. [ 7 ] Recent advances in inducing and harnessing Brillouin scattering in centimeter‐scale photonic chips [ 8–15 ] have enabled enhanced functionalities and advanced signal processing capability [ 16–18 ] for signal synthesis, [ 19,20 ] microwave photonic processing, [ 21–23 ] optical communication carrier regeneration, [ 24 ] signal storage, [ 25,26 ] and ultra‐sensitive detection. [ 27 ] New hybrid integration approaches allow for the co‐integration of lasers, [ 28 ] modulators, [ 29 ] detectors [ 30 ] and functional processing units, [ 22,31 ] providing the basis of a fully integrated Brillouin photonic chip that incorporates Brillouin‐active elements with functional photonic circuits, essential for enabling compact and robust signal processing systems.…”

On‐chip stimulated Brillouin scattering (SBS) that results from enhanced light–sound interactions, has recently demonstrated great applicability and versatility for signal generation and manipulation. Progress toward realizing fully integrated Brillouin photonic circuits is promising; however, the control and routing of on‐chip optical waves requires non‐reciprocal elements such as circulators, which is challenging and adds complexity. Here, a circulator‐free Brillouin photonic planar waveguide circuit which eliminates the need for separate non‐reciprocal elements is demonstrated. Backward inter‐modal Brillouin scattering (BIBS) is used in a planar photonic integrated circuit, for the first time, to provide Brillouin processing capability in a multi‐modal waveguide, conveniently allowing for the separation of counter‐propagating pump and signal using passive integrated mode‐selective filters. Using an As2S3–Si hybrid multi‐modal photonic circuit, inter‐optical‐mode energy transfer with a Brillouin gain coefficient of 280 m−1W−1 is experimentally demonstrated, representing two orders of magnitude enhancement compared to conventional optical fibers. This on‐chip BIBS circuit allows for independent routing of pump and signal waves, showing resilience to the cross talk. The experimental demonstrations provide an important basis for achieving fully integrated Brillouin photonic circuits without requiring on‐chip circulators and fine spectral filtering, opening a new dimension for studying spatial‐dependent photon–phonon nonlinear dynamics.

“…Benefit from the advantages of large bandwidth, low loss, and immunity to electromagnetic interference, microwave photonic channelizer receiver has attracted the attention of many scholars at home and abroad [12]- [14]. With the rapid development of microwave photonic integration technology, miniaturization and portability of channelized receivers will inevitably be the future development trend [15,16]. The reported microwave photonic channelization schemes can be divided into two categories.…”

The microwave photonic channelizer can convert the RF signal into the optical domain for transmission and procession, effectively avoiding the limitation of electronic bottleneck, and realizing the instantaneous reception of ultra-wideband signal or multi-frequency signals, which can be perfectly applied to radar system and electronic warfare. In this paper, a microwave photonic channelizer based on dual-output image-reject mixer is proposed, both the signal path and the local oscillator path are divided into three paths by using an optical coupler. An acousto-optic frequency shifter (AOFS) is used by the optical local oscillator to shift the frequency to the left and right and then enters the image rejection mixer with the signal path. Finally, a 6 GHz bandwidth RF signal is divided into six subchannels with a bandwidth of 1 GHz to achieve simultaneous reception. This scheme needs no optical frequency comb and doubles the channelization efficiency, the image rejection ratio of the sub-channels is about 22 dB, and the spurious-free dynamic range of the system can reach 103.2 dB• Hz 2∕3 .
