Master Student - AI Modeling for WSS and OCS Switching Systems (m/f/d)

Your mission

We are seeking a Master student to work on AI-driven modeling and optimization of metasurface-based Pixelated Isotropic LCOS (PI-LCOS) devices and Wavelength Selective Switch (WSS) systems. The project has two complementary tracks:

1. PI-LCOS metasurface optimization — Use AI techniques to optimize metasurface shapes and topologies to reduce insertion loss and achieve low polarization-dependent loss (PDL) in metasurface-based PI-LCOS devices.

2. WSS modeling & optimization — Develop AI-assisted models for WSS systems based on conventional LCOS technology, focusing on crosstalk suppression, insertion loss reduction, and system-level performance improvement.

• Develop AI/ML surrogate models and inverse design frameworks for metasurface unit-cell optimization targeting PI-LCOS devices, with objectives including insertion loss minimization and PDL reduction.

• Build and refine WSS system-level models (optical path, LCOS switching engine, port architecture) for conventional LCOS-based WSS, evaluating insertion loss, crosstalk, passband shape, and PDL

• Investigate WSS crosstalk suppression strategies through pixel layout design, phase/amplitude apodization, and AI-driven optimization.

• Perform electromagnetic simulations (FDTD, RCWA, FEM) of metasurface structures and validate AI predictions against full-wave results.

• Optimize metasurface geometry parameters (pillar shape, lattice, orientation, material) to minimize insertion loss and PDL while meeting phase/amplitude/polarization requirements.

• Apply AI/ML methods to the LCOS-based WSS design loop for multi-objective optimization across system-level performance metrics.

Your areas of expertise

• Enrolled in a Master's program in EE, Photonics, Applied Physics, Optical Engineering, CS, or related field.

• Deep learning fundamentals; experience with PyTorch or TensorFlow

• Familiarity with one or more: inverse design, physics-informed neural networks (PINNs), reinforcement learning

• Understanding of metasurface operating principles (phase/amplitude/polarization control via subwavelength structures).

• Knowledge of unit-cell design, lattice types, phase-gradient concepts, and fabrication constraints

• Foundational knowledge of physical optics, liquid crystal optics, and LCOS device operation (both conventional and pixelated isotropic modes).

• Understanding of WSS architecture and key metrics: insertion loss, crosstalk, bandwidth, PDL, port count.

• Experience with LC device modeling (Frank-Oseen theory, director simulation).

• Knowledge of DWDM systems and telecom optical component design

• Prior work at the intersection of AI and photonics/optics

• Ability to read technical literature independently.

• Ability to work independently and collaboratively in a research-oriented environment
