Integration of Optical Sensing into Orthopedic Surgical Devices

Knees and hips wear out. Backs and necks become unstable. Fortunately, orthopedic surgeons specialize in musculoskeletal repair. And surgeries that formerly required open exposure are now accomplished with minimally invasive techniques. Surgical risks are reduced, as are postoperative pain and recovery time.

Hyperchaos in the Mid-Infrared Regime Produced from Interband Cascade Lasers

Chaos, popular as butterfly effect, describes the irregular phenomenon of deterministic systems. Based on the unique features of sensitivity to initial conditions and unpredictability to future evolutions, chaos from laser diodes have found applications in private optical communication links, high-rate random number generations, Lidar systems, as well as recent optical computing networks.
