“…A temperature controller is used to change the temperature of the chip, so that the resonant wavelength of the microring resonator can be tuned. Meanwhile, it is also used to avoid the resonance drift during the experiment [29]. The power of the temperature controller is around 034053-2 MULTICHANNEL PHOTON-PAIR GENERATION.…”

We experimentally demonstrate a photon-pair source, based on continuous-wave pumped spontaneous four-wave mixing in a silicon microring resonator, which efficiently generates photon pairs with high coincidence counts, high brightness, and high coincidence-to-accidental ratio at multiple resonance wavelengths matching a standard International Telecommunication Union (ITU) frequency grid. The signal-idler joint spectral intensity is measured with a very high resolution of 2 pm over multiple wavelengths by an optical spectrum analyzer through probe-swept stimulated four-wave mixing, allowing an accurate quantification of the spectral correlation. Strong spectral correlation and uniform degree of quantum correlation are observed from the source, and the measured amount of spectral modes agrees well with that obtained by unheralded second-order correlation measurements.

“…In some resonant structures with third-order nonlinear optical materials, one given input state has two corresponding output states. Based on this unique property, OB can be applied to the fabrication of all-optical switches, memory cells, and transistors [ 1 , 2 , 3 , 4 , 5 , 6 ], which are the fundamental components of all-optical communication systems. Up to now, researchers have developed many different methods to realize OB, including ring cavities [ 7 , 8 ], photonic crystals [ 9 , 10 ], subwavelength waveguides [ 11 , 12 ] etc.…”

A kind of graphene-based perfect absorber which can generate low-threshold and high-extinction-ratio optical bistability in the near-IR band is proposed and simulated with numerical methods. The interaction between input light and monolayer graphene in the absorber can be greatly enhanced due to the perfect absorption. The large nonlinear coefficient of graphene and the strong light-graphene interaction contribute to the nonlinear response of the structure, leading to relatively low switching thresholds of less than 2.5 MW/cm2 for an absorber with a Q factor lower than 1000. Meanwhile, the extinction ratio of bistable states in the absorber reaches an ultrahigh value of 47.3 dB at 1545.3 nm. Moreover, the influence of changing the structural parameters on the bistable behaviors is discussed in detail, showing that the structure can tolerate structural parametric deviation to some extent. The proposed bistable structure with ultra-compact size, low thresholds, high extinction ratio, and ultrafast response time could be of great applications for fabricating high-performance all-optical-communication devices.

“…During the last decade, SiC has entered into integrated photonics, thanks to its beneficial optical properties of low material loss, relatively high refractive index, and wide transparent window. Compared to silicon, which is most widely used in integrated photonics, SiC, as a wide-bandgap semiconductor with both strong second-and third-order optical nonlinearities, does not suffer from two-photon absorption and subsequent free-carrier absorption in the telecom wavelength band, making this material suitable for high-power nonlinear applications [3], [4], [5], [6], [7]. These superior optical properties of SiC allow a variety of on-chip optical applications, for example, X. Shi, Y. Lu, K. Rottwitt and H. Ou are with DTU Fotonik, Technical University of Denmark, DK-2800 Lyngby, Denmark.…”

Silicon carbide (SiC), having various intrinsic color centers, is a highly promising optical materials for making monolithic quantum integrated photonic circuits, by combining the single-photon sources with the integrated photonic components in SiC integrated platforms. Based on this quantum-material platform, we propose polarization-independent 1 × 2 and 2 × 2 multimode interference based beam splitters and Mach-Zehnder interferometers (MZI) for single-photon manipulation with unknown polarization states. We experimentally demonstrate that these devices exhibit excellent performances with incident light at both high power (>-10 dBm) and ultra-low power (<-100 dBm). The 1 × 2 and 2 × 2 beam splitters have low average loss of 1 dB and 1.5 dB, with a wide bandwidth of >100 nm and >70 nm, respectively. The MZI exhibits high transmittance, with a visibility of 98.3% and 97.6% for the high-power measurement and an even higher visibility of 99.0 ± 0.4% and 98.7 ± 0.6% for the ultra-low power measurement, for the TE and TM polarizations, respectively.
