我國(guó)科研團(tuán)隊(duì)突破!全球首款全頻段高速光電融合通信芯片問世

在無線通信技術(shù)的最前沿,我國(guó)科研團(tuán)隊(duì)近日取得了里程碑式的成就。一項(xiàng)關(guān)于自適應(yīng)、全頻段、高速無線通信芯片的研究在國(guó)際頂級(jí)學(xué)術(shù)期刊《自然》上發(fā)表,標(biāo)志著我國(guó)在光電融合集成技術(shù)領(lǐng)域邁出了重要一步。

這項(xiàng)研究由北京大學(xué)電子學(xué)院教授王興軍與香港城市大學(xué)教授王騁攜手完成。他們突破性地構(gòu)建了一種全新的光電融合架構(gòu),使芯片實(shí)現(xiàn)了從“頻段受限”到“全頻兼容”的歷史性跨越。這一跨越意味著,無論用戶身處何地,都能享受到前所未有的高速、穩(wěn)定的通信服務(wù)。

研究團(tuán)隊(duì)提出的“通用型光電融合無線收發(fā)引擎”理念,依托先進(jìn)的薄膜鈮酸鋰光子材料平臺(tái),成功研發(fā)出一款超寬帶光電融合集成芯片。這款芯片尺寸雖小,僅指甲蓋大小(11mm × 1.7mm),卻集成了眾多關(guān)鍵功能,如寬帶無線-光信號(hào)轉(zhuǎn)換、可調(diào)諧低噪聲載波或本振源生成,以及數(shù)字基帶調(diào)制等,展現(xiàn)了極高的系統(tǒng)集成水平。

實(shí)驗(yàn)數(shù)據(jù)表明,基于該芯片構(gòu)建的無線通信系統(tǒng),其傳輸速率可達(dá)120Gbps以上,遠(yuǎn)遠(yuǎn)超出了當(dāng)前5G通信的速率,完全滿足了未來6G通信的峰值速率要求。更為重要的是,該芯片在全頻段內(nèi)保持了端到端無線鏈路的一致性能,即使在高頻段也未出現(xiàn)性能下降,為6G在太赫茲乃至更高頻段的頻譜資源高效利用提供了堅(jiān)實(shí)的技術(shù)支撐。

這一研究成果不僅標(biāo)志著我國(guó)在無線通信芯片領(lǐng)域取得了重大突破,更為下一代無線通信網(wǎng)絡(luò)的發(fā)展奠定了堅(jiān)實(shí)的基礎(chǔ)。隨著技術(shù)的進(jìn)一步成熟和應(yīng)用,我們有理由相信,更廣泛、更高效的通信連接將成為現(xiàn)實(shí),為人們的生活和工作帶來前所未有的便捷與高效。
