Active Optical Chips

Active optical chips (lasers & photodetectors) integrate micro-ball and aspheric lenses at emission/reception windows for high-efficiency mode-spot conversion and fiber coupling. C-lens collimators shape elliptical divergent light into collimated circular spots at the transmitter; hemispherical lenses widen receiving FOV at the receiver. Directly defining photoelectric conversion efficiency and bandwidth, they are core components for domestic optical chip substitution.

High-Speed Optical Transceivers

Ball and collimating lenses enable precision laser-to-fiber coupling in high-speed optical transceivers, supporting 800G/1.6T and faster optical interconnects. Multi-channel modules use collimating lenses for beam shaping and channel separation; aspheric lenses correct aberrations for PAM4 high-order modulation. Lens usage per module doubles with speed upgrades, making this a core growth driver for both volume and value.

Passive Optical Devices

Fiber connectors use ball/collimating lenses for beam expansion, reducing dust and end-face defect sensitivity while improving mating reliability. WDMs adopt a dual-lens architecture for wavelength multiplexing/demultiplexing. Optical isolators and circulators combine collimating lenses with polarizers for unidirectional transmission. Lens demand across all scenarios grows steadily with computing network expansion.

Co-Packaged Optics (CPO)

CPO co-packages optical engines with switch ASICs, lifting demands for optical path density and thermal stability, marking the cutting-edge lens application segment. Core solutions — microlens arrays (MLA), silicon-based lenses and optical interposers — enable multi-channel parallel coupling, high reflow temperature resistance and sub-micron alignment tolerance, forming the critical optical base for next-gen high-density optical interconnects.

Optical Amplifiers and Long-Haul Transmission

In EDFAs, pump combiners adopt collimating lenses for efficient pump-signal multiplexing and unrepeatered power compensation. Angled-end ball lenses suppress Fresnel reflection to shield gain fiber end-faces from backreflection damage. Raman amplifiers use hemispherical lenses to focus pump light, boosting non-linear gain for ultra-long-haul computing backbone transmission.

Optical Switches and All-Optical Switching

In MEMS and LC optical switches, collimating lenses deliver precise beam alignment between I/O fibers, supporting OXC nodes. Collimating lenses steer optical paths, while lens arrays enable high-density multi-channel layouts for large-scale port switching in compact spaces. Lens arrays guarantee consistent insertion loss across ports, acting as core coupling components for all-optical scheduling and flexible computing network routing.
