Modeling Expert in Fiber Optics for Simulation Software Engineering

VPIphotonics, a premier provider of professional simulation software for optical communication systems, offers a mid-level position in our R&D team.

Your activity:

Responsibilities
Development of mathematical models for various applications:

• Single-Mode Fibers for short-reach and long-haul transmission (SMF, NZ-DSF, DSF, DCF)
• Multimode Fibers MMF (OM3, OM4, OM5) for datacom applications
• Few-Mode Fibers (FMF) and Multicore Fibers (MCF) for Space Division Multiplexing (SDM)
• Fiber lasers and amplifiers based on rare-earth doped fibers and Raman amplification in
• single-mode, few-mode and multicore fibers.
• Distributed sensing (OTDR, phase-sensitive OTDR, OFDR)

Model prototyping, testing, documentation, and creation of application examples.
Contribution to externally funded R&D projects and publications at conferences and in journals.
