Highly motivated and results-oriented engineer with expertise in both research and development of optical systems. Seasoned Optical Engineer with over 3 years of expertise in designing, installing, and improving optical systems. Proficient in optical simulation design using Tracepro and Zemax, with a strong background in micro-optical technology research and development. Seeking to leverage my skills and experience to drive product innovation and development.

Optical Engineering Expertise (~4years):

• Optical Design & Simulation: Designed and simulated high-speed data transceiver lens modules (100G/200G/400G/800G) using Zemax and TracePro software, ensuring superior optical performance.

• Optical Metrology & Verification: Conducted detailed optical metrology and design verification tests to guarantee high optical coupling efficiency and precise tolerance measurements of lens products.

• Customer Solutions: Worked directly with customers to provide tailored optical solutions, addressing and resolving complex optical challenges.

• Beam Profile Measurements: Conducted beam profile measurements for customer light sources and developed accurate digital sources with far-field patterns for simulations.

• Simulation & Design Verification: Utilized TracePro for comprehensive optical simulations and SolidWorks for robust design verification, enhancing product reliability.

• Innovative System Development: Established the POF preparation and assembly system for HDMI cables, the first implementation in the company, significantly improving product offerings.

• Grew single crystals using various techniques (floating zone, Bridgman) and characterized them using XRD, Laue, and other measurement systems (Research Assistant Job).
• Performed thin-film deposition using CVD and PVD for 2D materials and conducted spectroscopic analysis to determine material properties relevant to optoelectronic devices (Research Assistant Job)
