    Fujia Gallium's Gallium Oxide Epitaxial Wafer Passes Lateral MOSFET Power Device Validation

    Fujia Gallium's MBE gallium oxide epitaxial wafer has completed validation in lateral MOSFET power devices. A device with a 12 μm gate-drain spacing achieved a breakdown voltage of 2242 V, a current density of 60 mA/mm and a specific on-resistance of about 42 mΩ∙cm², on par with comparable imported materials. The wafer uses a composite double-layer structure of an unintentionally doped layer and a Sn-doped layer on a semi-insulating (010) Fe-doped gallium oxide substrate. Standard products feature a doped-layer carrier concentration of 1-4E17 cm⁻³, mobility above 80 cm²/V·s and surface roughness below 2 nm.

    Fujia Gallium Grows 3-Inch Gallium Oxide Single Crystal by Vertical Bridgman Method for First Time in China

    In July 2024, Hangzhou Fujia Gallium Technology Co., Ltd. became the first company in China to grow a 3-inch gallium oxide single crystal using the vertical Bridgman (VB) method, and developed VB gallium oxide crystal growth equipment based on simulation technology. VB growth requires no iridium, greatly reducing costs, while its uniform temperature field and small temperature gradient make it easier to grow large, high-quality crystals and suit automated, large-scale production. The company had previously mastered edge-defined film-fed growth (EFG) technology for 6-inch conductive and insulating gallium oxide substrates, as well as EFG one-click crystal growth equipment.

    Aio Optics Introduces SpectrumShaper-R4 Spectral Broadening Module

    Aio Optics has introduced the SpectrumShaper-R4 series spectral broadening module, extending the broadening range from 1-30 GHz to 1-80 GHz. An integrated single-frequency seed source is available as an option, and the built-in spectral profiles and software interaction have been optimized. Aimed at high-power narrow-linewidth fiber lasers, the module controls the seed spectrum through electro-optic phase modulation of an RF signal to suppress nonlinear effects during amplification.

    Why we recommend it: Changes in the broadening range and integrated seed-source options correspond to specific design requirements for narrow-linewidth fiber lasers, useful for comparing trade-offs between spectral control and full-system integration.

    Progress in Passively Mode-Locked Laser Technology with Ring Cavities at Suzhou Institute of Nano-Tech

    A team at the Suzhou Institute of Nano-Tech, Chinese Academy of Sciences, has developed a theoretical model for PML-SRLs, revealing that operating states are governed by the temporal balance of gain and loss. The model combines time-domain traveling-wave equations with partial differential equations for carrier density, examining the relationship among SOA carrier accumulation rate, SA carrier lifetime and ring-cavity round-trip time. The work, published in Optics Express, also found that an SOA with a narrow gain spectrum and a short resonator configuration can merge output pulses to yield high-energy optical pulses.

    Why we recommend it: Putting gain, absorber and cavity round-trip time into a unified dynamic model offers transferable design insight for understanding mode-locking states and pulse merging in semiconductor ring cavities.

    Spatial Light Modulators in Three Minutes

    A spatial light modulator (SLM) uses liquid crystal materials driven electrically to change the amplitude, phase or polarization state of light waves, modulating the spatial distribution of a beam. Amplitude SLMs use TN and VA modes, phase SLMs use ECB mode, and reflective optical paths generally require an oblique incidence angle of less than 5°. The device has been used in 3D printing and lithography, super-resolution microscopy, holographic imaging and atmospheric turbulence simulation.
