Siddharth Ramachandran

Siddharth Ramachandran is a Professor in Electrical and Computer Engineering at Boston University, leading the High Dimensional Photonics Lab where he studies light beams with spatio-temporal complexity and their applications. His lab focuses on singular optics, structured microscopy, and nonlinear/quantum photonics.

Research interests include:

• Orbital angular momentum manipulation
• Nonlinear optical processes in fibers
• Quantum light generation
• Topological confinement phenomena
• High-dimensional quantum communication

Recent publications demonstrate advances in mode-division multiplexing, fiber-based quantum sources, and machine-learning optimized optical systems. Work focuses on scaling mode capacity in optical fibers, developing novel light sources, and exploring topological effects in photonics.

His group maintains collaborations across photonics and quantum optics research communities to develop next-generation optical technologies.
