Intern, Digital Twin of Liquid Crystal Optical Circuit Switch (OCS)

Primary Duties & Responsibilities

Develop a digital twin model for Liquid Crystal-based optical circuit switching architectures, including spatial light modulators, LC beam steering devices, and free-space optical relay systems.

Model free-space optical propagation and system performance using optical design tools such as Zemax OpticStudio or equivalent ray-tracing platforms.

Investigate polarization-diverse switching architectures to support polarization-insensitive operation and improve switching efficiency and scalability.

Simulate electro-optic behavior of liquid crystal devices, including phase modulation, birefringence control, and beam steering mechanisms.

Explore co-design methodologies that jointly optimize LC device physics and system architecture, including device parameters, optical layout, and switching fabric topology.

Analyze key optical system parameters including:


* beam propagation and diffraction


* polarization effects and birefringence


* insertion loss and crosstalk


* switching contrast ratio


* optical alignment tolerances and stability

Perform tolerance and sensitivity analysis to evaluate the impact of optical alignment, mechanical stability, and thermal variation on switching performance.

Use finite element analysis (FEA) tools (e.g., ANSYS, COMSOL) to model thermal effects, mechanical deformation, and packaging influences that may impact optical alignment or LC device behavior.

Investigate AI-assisted digital twin modeling approaches, including machine learning techniques to accelerate simulation, predict device/system performance, and optimize switching architectures.

Develop modeling and simulation frameworks using Python, MATLAB, or scientific computing environments.

Collaborate with optical, device, and system engineers to refine models and validate simulation results against experimental measurements.

Document research methodology and findings.

Deliver a final technical report and presentation summarizing the digital twin architecture, modeling framework, and design insights for next-generation LC-based OCS systems.
