“…A similar discussion is held in the cw pump regime [42] in which g (2) (0) 1+ 1 M was derived with the assumption of the detectors having the finite temporal resolution, where M represents the number of the cavity mode. These results look giving the same formula and have been applied for many experiments using pulse laser [7,51] and cw laser [28,52,53]. Here we show another formula for the cw pump regime, which is independent of the temporal resolution of the detectors.…”

Biphoton frequency comb (BFC) having quantum entanglement in a high dimensional system is widely applicable to quantum communication and quantum computation. However, a dozen mode realized so far has not been enough to realize its full potential. Here, we show a massive-mode BFC with polarization entanglement experimentally realized by a nonlinear optical waveguide resonator.The generated BFC at least 1400 modes is broad and dense, that strongly enhances the advantage of BFC. We also demonstrated a versatile property of the present BFC, which enables us to prepare both the frequency-multiplexed entangled photon pair and the high dimensional hyperentangled one. The versatile, stable and highly efficient system with the massive-mode BFC will open up a large-scale photonic quantum information platform.

“…We expect that progress in nonlinear integrated photonics will occur along three paths: one involving new materials and new physics in nonlinear interactions; a second devoted to improving device performance using well-known and innovative guided-wave nonlinear optical schemes; and a third addressing new perspectives in quantum photonics. In this regard, being impossible to adequately cover the achievements in quantum optics in this short review, we just mention a few examples, all exploiting the exceptional characteristics of microring resonators, either on a silicon platform [ 206 , 207 ] or a 4H-SiC-on-insulator platform [ 208 ]. Quantum technologies may well exploit other materials as well, and we refer interested readers to an extended review on the 2023 roadmap for materials for quantum technologies, published in January 2023 [ 209 ].…”

The combination of integrated optics technologies with nonlinear photonics, which has led to growth of nonlinear integrated photonics, has also opened the way to groundbreaking new devices and applications. In a companion paper also submitted for publication in this journal, we introduce the main physical processes involved in nonlinear photonics applications and discuss the fundaments of this research area. The applications, on the other hand, have been made possible by availability of suitable materials with high nonlinear coefficients and/or by design of guided-wave structures that can enhance a material’s nonlinear properties. A summary of the traditional and innovative nonlinear materials is presented there. Here, we discuss the fabrication processes and integration platforms, referring to semiconductors, glasses, lithium niobate, and two-dimensional materials. Various waveguide structures are presented. In addition, we report several examples of nonlinear photonic integrated devices to be employed in optical communications, all-optical signal processing and computing, or in quantum optics. We aimed at offering a broad overview, even if, certainly, not exhaustive. However, we hope that the overall work will provide guidance for newcomers to this field and some hints to interested researchers for more detailed investigation of the present and future development of this hot and rapidly growing field.

Silicon carbide (SiC) is emerging rapidly in novel photonic applications thanks to its unique photonic properties facilitated by the advances of nanotechnologies such as nanofabrication and nanofilm transfer. This review paper will start with the introduction of exceptional optical properties of silicon carbide. Then, a key structure, i.e., silicon carbide on insulator stack (SiCOI), is discussed which lays solid fundament for tight light confinement and strong light-SiC interaction in high quality factor and low volume optical cavities. As examples, microring resonator, microdisk and photonic crystal cavities are summarized in terms of quality (Q) factor, volume and polytypes. A main challenge for SiC photonic application is complementary metal-oxide-semiconductor (CMOS) compatibility and low-loss material growth. The state-of-the-art SiC with different polytypes and growth methods are reviewed and a roadmap for the loss reduction is predicted for photonic applications. Combining the fact that SiC possesses many different color centers with the SiCOI platform, SiC is also deemed to be a very competitive platform for future quantum photonic integrated circuit applications. Its perspectives and potential impacts are included at the end of this review paper.
