Ultrafast Optics and Optical Fiber Communications Laboratory

Research in the Ultrafast Optics Laboratory focuses on the technology and applications of ultrafast laser pulses on the femtosecond time scale (1 femtosecond = 10^-15 seconds). We are particularly active in developing and applying technologies for manipulating and processing femtosecond lightwave signals.

Purdue ECE researchers develop technique for more precise ToF measurements

High precision time-of-flight measurements realized on entangled photons || Purdue ECE

Ultrafast lab members and collaborators have developed a technique to make time-of-flight measurements (ToF) of entangled photons where the precision of the measurement dramatically exceeds the resolution of commercially available single-photon detectors. These results were published in Optica.
