Strategic Objectives
• Master the physical architecture of PIN and Avalanche Photodiodes.
• Minimize signal degradation by isolating and neutralizing noise sources.
• Optimize responsivity and quantum efficiency for peak sensor performance.
• Overcome the physical bottlenecks of optoelectronic conversion bandwidth.
