Optical Design Engineer

Key Responsibilities:

• Optical Architecture Design: Design the free-space optical path based on MEMS arrays, digital liquid crystal, etc., including the design of core components such as MLA, FAU, and lenses.
• Simulation & Tolerance Analysis: Perform simulations and evaluate system coupling efficiencies using Zemax or other optical design tools. Conduct rigorous optical tolerance analysis to provide precise alignment requirements for mechanical design and assembly processes. Design the monitoring systems integrated in a close-loop or supervised OCS architecture.
• Performance Optimization: Perform root-cause analysis from an optical physics perspective to address performance bottlenecks (e.g., IL, PDL, Crosstalk, TDL etc.) in early prototypes (V0.0/V0.1).
• Design for Manufacturability (DFM) & Scale-up: Collaborate with core optical component suppliers to align technical specifications and release rigorous optical drawings. Drive the transition of the optical engine from Proof of Concept (PoC) to mass production. Optimize tolerance budgets, and collaborate closely with the process team to ensure the design is scalable, cost-effective, and manufacturable with high yield in a volume production environment.

Qualifications

• Bachelor's degree or above in Optical Engineering, Optoelectronics, Physics, or a related field.
• Proficiency in optical design software such as Zemax or Code V; deep understanding of Gaussian beam propagation and single-mode fiber coupling
• Proven experience in designing free-space optical communication devices (e.g., WSS, OXC, Optical Switches, Coherent Transceivers), with a strong grasp of DFM principles and cost-reduction strategies
• Knowledge of MEMS working principles and their impact on optical path design is highly preferred.
