PIC fan-out transfer optical wavegui♠≤de chip is based on the femtosecond laser•δ₹ direct writing technology master∏≤©ed by Shenzhen Photonics V♥÷δalley. It can match self-developed PIC, mainstre∏φ♠♥am PIC, customize FA, MT ferrule, ♣≤Ω©MCF and other chips, device end-face$€ optical port arrangement, ♦σ€Ωrealize the processing and preparation o¶≈f arbitrary three-dimensional shape structure, an™λ£¥d provide possibilities for the fan-in ↓φ and fan-out requirements of optical≥$ chips. Through femtosecond laser direct writin ≤g technology, miniaturized, low₽ -loss three-dimensional optical waveguide ch↓♥↑±ips with low transmission l₽↕oss, circular cross-section and high∑∏ symmetric mode field can be ≤∑prepared on glass substrates, which is of great↔≈→δ significance for the realization of×↑₹ high-density optical interconnect produc$∞∏£ts.
