We propose a scheme to phase lock a quantum-memory control laser, frequency-conversion pump laser, and two-photon source over three octaves in frequency to operate a quantum memory. The absolute frequencies of the laser sources are determined based on a Doppler-free iodine hyperfine transition. The achieved relative frequency instability and uncertainty were ≤1 × 10–12 and 3 × 10–11, respectively, which are below the requirement for operating a Pr:YSO quantum memory. This scheme simplifies the instrumentation of laser sources in a quantum repeater, and increases the reliability of quantum communication systems.
我们提出了一种将量子存储器控制激光器、频率转换泵浦激光器和双光子源的相位锁定在三个倍频程上的方案,以运行量子存储器。激光源的绝对频率是根据无多普勒碘超频跃迁确定的。获得的相对频率不稳定性和不确定性分别≤1 × 10-12 和 3 × 10-11,低于运行 Pr:YSO 量子存储器的要求。该方案简化了量子中继器中激光源的仪器,提高了量子通信系统的可靠性。

We report on an approach to produce single photon emitters at the SiO2/SiC interface. We form a high-quality SiO2/SiC interface by high-temperature oxidation and subsequently perform oxidation at lower temperatures (200 °C–1000 °C) to generate the emitters. After reoxidation at 800 °C, we confirmed the formation of emitters with a bright luminescence (>50 kcps). Through Hambury-Brown and Twiss measurements, single photon characteristics were confirmed. Thus, the proposed approach is effective in generating highly bright single photon emitters at the SiO2/SiC interface.
我们报告了一种在二氧化硅/碳化硅界面上产生单光子发射器的方法。我们通过高温氧化形成了高质量的二氧化硅/碳化硅界面,随后在较低温度(200 ℃-1000 ℃)下进行氧化以产生发光体。在 800 °C 再氧化后,我们确认形成了具有明亮发光(50 kcps)的发光体。通过 Hambury-Brown 和 Twiss 测量,证实了单光子特性。因此,所提出的方法能有效地在二氧化硅/碳化硅界面上产生高亮度的单光子发光体。

Two-dimensional (2D) material is drawing considerable attention as a promising thermoelectric material. This study establishes the formation method of renewed Ca-intercalated group IV 2D materials, Ca(Ge1−xSnx)2 crystals including germanene-based 2D layers. The solid phase epitaxy allows us to form epitaxial Ca(Ge1−xSnx)2 on Si. Atomic force microscopy reveals that the Ca(Ge1−xSnx)2 has island structures. X-ray diffraction proved the epitaxial growth of the Ca(Ge1−xSnx)2 island structures and the increase of the c-axis lattice constant with Sn content increase. The formation of this renewed intermetallic compound including group IV 2D layer opens an avenue for high performance thermoelectric generator/Si.

We demonstrate a master oscillator power amplifier system that emits single-frequency, high-energy optical pulses at 1539 nm using an Er, Yb:glass planar waveguide amplifier with a normalized frequency of the waveguide of 4.4. A maximum pulse energy of 9.7 mJ is observed at a repetition frequency of 500 Hz. The signal to noise ratio is 25 dB and is independent of the repetition frequency from 100 to 500 Hz. The beam quality factor M2 of the output is 1.03 thanks to the small normalized frequency of the planar waveguide.

1550 nm wavelength photonic-crystal surface-emitting lasers (PCSELs) are attractive for optical communication and eye-safe sensing applications. In this study, we present InP-based PCSELs featuring a double-lattice photonic-crystal structure designed for high-power single-mode operation at a wavelength of 1550 nm. These PCSELs demonstrate output powers exceeding 300 mW under continuous-wave conditions at 25 °C. Additionally, highly stable single-mode oscillation with a side-mode suppression ratio of over 60 dB is verified at temperatures from 15 °C to 60 °C. Measurement and simulation of photonic band structures reveal the impacts of the threshold gain margin and optical coupling coefficient on the single-mode stability.

We report on a passively mode-locked Tm,Ho:CLNGG laser operating at 2090 nm, pumped by a multimode fiber-coupled 793 nm laser diode, representing the first demonstration of a diode-pumped sub-100-fs mode-locked laser at 2.1 μm wavelength. Due to the disordered nature of the gain material that exhibits a broad and smooth gain profile, pulses as short as 88 fs were achieved with an average output power of 120 mW at a repetition rate of 70.3 MHz. Stable self-starting mode-locked operation was obtained using a semiconductor saturable absorber mirror based on the GaSb material system.

The functionalities of materials are governed by the atom type and arrangement, and perturbations caused by defects and adsorbate interactions often significantly alter the behavior of materials. Scanning probe microscopy (SPM) can capture complex interactions caused by the structures on surfaces. It is, however, difficult to analyze such interactions appearing there. In this paper, an image-processing technique that employs template matching to recognize local structures in SPM images and calculate positional correlations is reported. This approach opens new avenues for investigating intricate perturbations in the sciences and provides detailed insights into materials science.

Artificial lattices with semiconductor spacers are expected to exhibit changes in their magnetic structure owing to the control of their electronic states. The temperature (T) and magnetic-field (Hext) dependence of the in-plane magnetic structure of an [Fe3Si/FeSi2]20 superlattice with a nonmagnetic and semiconducting FeSi2 spacer layer is investigated using magnetization and polarized neutron reflectivity measurements. When Hext = 5 mT, nearly collinear antiferromagnetic (AF) structures are observed from 4 to 298 K. When Hext = 1 T, field-induced fan-like, noncollinear AF structures showing ferromagnetic components along Hext and transverse AF components are observed at low T.
由于电子状态的控制,带有半导体间隔物的人工晶格预计会表现出磁性结构的变化。我们使用磁化和偏振中子反射率测量方法研究了带有非磁性和半导体 FeSi2 间隔层的 [Fe3Si/FeSi2]20 超晶格的面内磁结构的温度(T)和磁场(Hext)依赖性。当 Hext = 5 mT 时,在 4 至 298 K 范围内观察到近乎共线的反铁磁(AF)结构。当 Hext = 1 T 时,在低 T 时观察到场诱导的扇形非共线 AF 结构,显示出沿 Hext 的铁磁成分和横向 AF 成分。
