GRAFT-Stereo: Cost-Effective, High-Accuracy 3D Depth Perception
TS-071747 — The Need
High-accuracy 3D depth perception is critical for autonomous systems, but current stereo camera methods falter in complex outdoor environments. While LiDAR can improve accuracy, its effectiveness plummets when using sparse data from affordable, lower-beam sensors, making high performance …

Antimonide based Separate Absorption Charge and Multiplication Avalanche Photodiode
TS-062892 — A room temperature, ultra-high gain (M=278, λ=1550 nm, V=69.5 V, T=296 K) linear mode avalanche photodiode (APD) on an InP substrate using a GaAs0.5Sb0.5/Al0.85Ga0.15As0.56Sb0.44 separate absorption charge and multiplication (SACM) heterostructure.
An APD is a semiconductor-based analog of the photomultiplier. APDs exploit the impact ionization phenomenon and transform infrared (IR) light (l > 850 nm) into photocurrent. APDs have wide applicability; however, existing APDs have insufficient sensitivity and relatively high excess noise an…
