IdealPhotonics' near-infrared high-speed detector, based on InGaAs or Ge fast-response devices (bandwidth > 1 GHz), achieves nanosecond-level rise times through optimized junction capacitance and carrier transit time, making it suitable for fiber optic communication (1550 nm) and laser ranging.GHz-level bandwidth and low timing jitter (< 50 ps) are achieved, but temperature control is required to suppress dark current.
