Lens and optical system design, aberration correction and simulation.
Robot vision solutions company Lianhe Imaging has completed a financing round worth several hundred million yuan, with investors including Dunhong Capital, and annual revenue of about 2 billion yuan.
Guangna Siwei has completed a Series A round of nearly 200 million yuan, with investment from Guangzhou Industrial Investment, Guangzhou Financial Holdings and others, to develop full-color optical waveguides.
Lijing Innovation is again pursuing a Hong Kong IPO, though its rapid growth is accompanied by questions over its reliance on the Apple supply chain and its independence.
Yutong Optics established Shenzhen Yutong Optical Interconnect Technology on July 7, marking two strategic moves within a month.
Nika Optics has completed a Series A round of nearly 100 million yuan, with investors including BOCI, breaking the overseas blockade on volume holographic materials.
A team led by Associate Researcher Luo Jing at the Changchun Institute of Optics, Fine Mechanics and Physics published a paper in Optics and Lasers in Engineering using the low-frequency polarization aberration produced by plane mirrors in non-parallel optical paths to compensate for the polarization aberration of the optical system itself. In design verification of a typical off-axis three-mirror system, adding a plane mirror and adjusting its pose reduced the system's polarization aberration to 1/15 of its original value, with the full-field average phase retardance dropping from 0.0759 rad to 0.0050 rad, while wavefront aberration and optical efficiency were essentially unaffected.
Shanghai Yitong Photonics Technology Co., Ltd. and RX Global have formed a strategic partnership to co-host Photonics World Asia 2024. Held as a preview edition, the show will take place from November 6 to 8, 2024 at the Shenzhen World Exhibition and Convention Center (Bao'an), alongside six RX flagship exhibitions. The event focuses on laser technology and applications, optical systems and precision optics, precision machinery and motion control, and test, measurement and sensing technology. It is expected to attract 10,000 professional visitors from China and abroad, with industry conferences on laser applications in touchscreens, semiconductor manufacturing and other fields.
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.
Focuslight, Synopsys, AMS Technologies and Oxford Instruments announced or completed acquisitions in early 2024, covering micro- and nano-optics, simulation software, laser systems and scientific cameras. Focuslight completed the acquisition of 100% of the equity in SMO for EUR 75.5405 million, while Synopsys plans to acquire Ansys for $35 billion, a deal still subject to shareholder and regulatory approval. AMS Technologies acquired neoLASE, and Oxford Instruments acquired First Light Imaging.
Why we recommend it: The four deals respectively add device manufacturing, simulation software, laser system and scientific imaging capabilities, useful for comparing different paths optics companies take to expand through acquisitions.
