Silicon Photonics Scientist

About Silicon Photonics Business Division

Delta Silicon Photonics Business Division develops world-class silicon photonics chips and solutions that power next-generation sensors and intelligent systems. Our mission is to deliver smarter and safer environments — from machines and infrastructure to everyday life — by translating advanced silicon photonics into real-world impact that benefits people. We are a future-focused, innovative, and entrepreneurial team driven by deep technology expertise, bold execution, and a strong sense of purpose.

What You’ll Be Doing

As a Scientist in System Architecture, you will be the system-level visionary for our FMCW LiDAR optical engines. You will translate product requirements into a cohesive architectural blueprint, defining how the silicon photonics core, the laser source, and the electronic processing chain interact to achieve long-range, high-precision sensing. You will bridge the gap between photonic device physics, hardware constraints, and end-user system performance.

What It’s Like Working With Us

You’ll work in a highly technical, fast-moving environment where problems are complex and solutions are not always predefined. Collaboration is essential across engineering, product, operations, and supply-chain teams, and progress depends on clear thinking, trust, and ownership.

We value curiosity and continuous learning, and we expect team members to be comfortable navigating ambiguity, testing assumptions, and improving through iteration. People here are encouraged to take initiative, learn quickly from both successes and setbacks, and shape how work gets done.

Key Responsibilities

• System-Level Architecture & Link Budget: Ownership of the end-to-end FMCW LiDAR optical and electrical link budgets. Translate system specifications (range, resolution, frame rate) into explicit requirements for optics, PIC, lasers, and electronics.
• Performance Modeling & Simulation: Develop comprehensive mathematical and physical system models to simulate ranging performance, SNR, maximum detectable range, velocity ambiguity, and point-cloud density.
• Silicon Photonics Specification: Partner with PIC designers and laser experts to define photonic device specifications (laser linewidth, chirp linearity, optical insertion loss, photodetector responsivity, optical crosstalk).
• System Trade-off Analysis: Drive cross-functional trade-off decisions between laser sweep bandwidth, power budget, optical aperture size, dynamic range, and digital processing complexity.
• Next-Generation Architecture Exploration: Lead technical feasibility studies for next-generation FMCW concepts, evaluating emerging optical beam steering (e.g., OPA), advanced modulation schemes, and photonic integrated circuit architectures.

Qualifications

• Education: Bachelor’s degree or higher in Optical Engineering, Photonics, Electrical Engineering, Physics, or a related discipline.
• Experience: 3+ years of relevant experience in optical system engineering, LiDAR architecture, or coherent optical communication systems.
• Technical Expertise:
• Deep theoretical foundation in FMCW physics, optical coherence, laser phase noise, and detection theory.
• Strong working knowledge of Silicon Photonics (SiPh) component characteristics and limitations.
• Proven experience building system-level numerical models in Python or MATLAB.
• Hands-on experience with optical simulation tools (e.g., Lumerical, Zemax) is highly desirable.
• Soft Skills: Excellent analytical framing, strategic technical clarity, and the ability to articulate complex physical trade-offs to multidisciplinary engineering teams.
