單片集成 6 比特光延時芯片

Single-chip Integrated 6 Bit Optical Delay Chip

〖簡介Introduction〗

梓冠光電的單片集成 6 比特光延時芯片是基于厚膜 SOI 硅光子技術(shù)、將硅基光開關(guān)和硅波導(dǎo)延時路單片集成的自主研發(fā)產(chǎn)品。集成的硅基光開關(guān)使其延時態(tài)切換速度達到 1 μs 以下，硅波導(dǎo)延時使其延時精度提升 1 個量級，厚膜 SOI 硅光技術(shù)使其光損耗達到工程應(yīng)用水平，單片集成的芯片解決了傳統(tǒng)光延時器的體積大、可靠性差問題，是可全方面滿足光控相控陣應(yīng)用要求的新一代產(chǎn)品。

The single-chip integrated 6-bit optical delay chip of Ziguan Photonics is an independently developed product based on thick film SOI silicon photonics technology, which integrates silicon based optical switches and silicon waveguide delay circuits on a single chip. The integrated silicon based optical switch achieves the delay state switching speed less than 1 μs, the delay of silicon waveguide improves its delay accuracy by one order of magnitude, and the thick film SOI silicon optical technology enables the optical loss to reach the level of engineering application. The single chip integrated chip solves the problems of large volume and poor reliability of traditional optical delay devices, and is a new generation product that can fully meet the application requirements of optically contronlled phased array.

〖2×2 光開關(guān)（圖 1）的“交叉"、“直通"傳輸狀態(tài)定義如下〗

〖The "Cross" and "Bar" transmission states of the 2×2 optical switch (Figure 1) is defined as follows〗

“交叉"狀態(tài)（Cross 態(tài)）：從輸入 A 端輸入，輸出端 D 有光信號輸出，輸出端 C 沒有光信號輸出時，即為"交叉“態(tài)（A→D）；類似定義，從輸入端 B 輸入，輸出端 C 光信號輸出，輸出端 D 沒有光信號輸出，也為"交叉“態(tài)（B→C）。

“直通"態(tài)（bar 態(tài)）：從輸入端 A 處輸入，輸出端 C 有輸出光信號，輸出端 D 沒有光信號輸出時，即為"直通“態(tài)（A→C）；類似定義，從輸入端 B 輸入，輸出端 D 有光信號輸出，輸出端 C 沒有光信號輸出，也為“直通"態(tài)（B→àD。
