The heterogeneous integrated silicon -based lithium pheasant platform is a physical carrier for developing multi -functional microelectronic chips. It can be widely used in 5G/6G communication radio frequency filter chip, optical chip of data centers in the era of large models, high -performance iron power storage chips and quantum quantum.chip.Ou Xin team, a researcher at the Shanghai Institute of Micro System and Information Technology of the Chinese Academy of Sciences, has made breakthroughs in the field of lithium pheasantic acid integrated wafer and high -performance photon chip preparation.More advantage with batch preparationEssenceRelated results were published in the international academic journal “Nature” on May 8.
With the development of the global integrated circuit industry in Moore, the difficulty and cost of the performance of integrated circuit chips are increasing, and integrated optoelectronics technology represented by silicon optical technology and lithium film lithium photon technology is to respond to this bottleneck problemUnder subversive technology.Among them, lithium cricket acid is known as “optical silicon”, and has received widespread attention in recent years.Ou Xin team and collaborators have proved that similar to lithium lithium, monocrystalline lithium -lithium film also has excellent electro -light conversion characteristics.
“Compared to lithium film chillate, the lithium film is easier to prepare, and the preparation efficiency is more efficient. At the same time, lithium pyrodolite film has a wider transparent window, strong electric light preparation, weak dual refraction, stronger light resistance discountsFeatures, this congenital material advantage has greatly expanded the lithium lithium platform’s optical design freedom. “Ou Xin said.Based on the heterogeneous integrated technology of “Universal ion knife”, the scientific research team prepared high -quality silicon -based single -crystal thin -film heterogeneous wafers, and jointly developed the micro -nable processing method of ultra -low lithium lithium lithium photon device with the cooperative teamThe optical loss of the corresponding device is lower than the minimum loss value of the wafer -grade lithium rigidate reported by other teams.
Lithium lithium photon chip not only shows the comparable electric light modulation efficiency as the lithium lithium film, but also based on the lithium lithium photon photon chip.The nature is expected to be applied in the aspects of laser radar and precision measurement.
