Single-chip Integrated 7 Bit Optical Delay Chip

〖簡介Introduction〗

梓冠光電的單片集成多比特光延時(shí)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(shí)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(shí)態(tài)切換速度達(dá)到 1 μs 以下，硅波導(dǎo)延時(shí)使其延時(shí)精度提升 1 個(gè)量級(jí)，厚膜 SOI 硅光技術(shù)使其光損耗達(dá)到工程應(yīng)用水平，單片集成的芯片解決了傳統(tǒng)光延時(shí)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 multi-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.

〖主要性能指標(biāo) Specifications〗

1、精度與延遲的權(quán)衡：光柵尺的精度越高，其測量結(jié)果的準(zhǔn)確性就越高，但同時(shí)也會(huì)帶來更大的延遲。因此，在實(shí)際應(yīng)用中，需要根據(jù)具體需求選擇合適的精度和延遲。

  2、環(huán)境適應(yīng)性：光柵尺延遲線對(duì)環(huán)境溫度、濕度等環(huán)境因素較為敏感，因此在實(shí)際應(yīng)用中需要注意環(huán)境因素的影響。

  3、穩(wěn)定性與可靠性：光柵尺延遲線具有較高的穩(wěn)定性和可靠性，能夠長時(shí)間穩(wěn)定工作，保證測量結(jié)果的準(zhǔn)確性。
