The excellent optical and unique material properties of lithium niobate have long established it as a prevailing photonic material, especially for the long‐haul telecom modulator and wavelength‐converter applications. However, conventional lithium niobate optical waveguides are bulky, hence large‐scale photonic circuit implementations are impeded and high power requirements are imposed. To address these shortcomings, thin‐film lithium niobate technology has been a topic of intense research in the last few years and a plethora of ultracompact devices with significantly superior performances than the conventional counterparts have been demonstrated. These efforts have rejuvenated lithium niobate for novel electro‐, nonlinear‐, and quantum‐optic applications. Herein, the most recent advancements of this booming field are summarized and a perspective for future directions is given.

“…In recent years, photonic devices based on LNOI, including waveguides [6,7], microring resonators [1,8], microdisk resonators [9][10][11], and photonic crystal cavities [12,13] have been developed. On-chip functionalities, such as second harmonic generation [13][14][15][16][17][18], electro-optic modulator [3,[19][20][21][22][23], and optical frequency comb [24,25], have experienced rapid progress with the above-mentioned LNOI micro-/nanodevices. Importantly, many integrated on-chip lithium niobate (LN) devices developed recently already feature low propagation losses [6][7][8]10], which is critical for practical applications.…”

A lithium niobate on insulator ridge waveguide allows constructing high-density photonic integrated circuits thanks to its small bending radius offered by the high index contrast. Meanwhile, the significant mode-field mismatch between an optical fiber and the single-mode lithium niobate waveguide leads to low coupling efficiencies. Here, we demonstrate, both numerically and experimentally, that the problem can be solved with a tapered single mode fiber of an optimized mode field profile. Numerical simulation shows that the minimum coupling losses for the TE and TM mode are 0.32 dB and 0.86 dB, respectively. Experimentally, though without anti-reflection coating, the measured coupling losses for TE and TM mode are 1.32 dB and 1.88 dB, respectively. Our technique paves a way for a broad range of on-chip lithium niobate applications.

“…Until recently, silicon photonics has been the main platform for PIC applications owing to its compatibility with the mature complementary-metal-oxidesemiconductor (CMOS) technology [1,2]. In the meantime, lithium niobate (LN) photonics has been emerging as an alternative and/or complementary approach for realizing large-scale PICs, thanks to the recent advances in the development of fabrication technologies of high quality photonic microand nanostructures such as low-loss waveguides and high quality factor (Q factor) microresonators on lithium niobate on insulator (LNOI) [3][4][5][6][7][8][9][10][11][12].…”

We report fabrication of a multifunctional photonic integrated chip on lithium niobate on insulate (LNOI), which is achieved by femtosecond laser assisted chemo-mechanical polish. We demonstrate a high extinction ratio beam splitter, a 1 × 6 optical switch, and a balanced 3 × 3 interferometer on the fabricated chip by reconfiguring the microelectrode array integrated with the multifunctional photonic circuit.
