Photodetector Bandwidth describes how quickly a detector can respond to rapid changes in optical signal intensity, defining the maximum frequency or data rate the device can accurately follow. It is determined by factors including junction capacitance, load resistance, carrier transit time, and packaging parasitics. GPD engineers photodetectors with carefully controlled geometry and packaging to achieve bandwidths ranging from kilohertz to multiple gigahertz, meeting the performance requirements of applications from low-speed spectroscopy and industrial sensing to high-speed LiDAR ranging and multi-gigabit optical communications.
