Session: (In-Person) Oral Panel—Uniquely Their Own
An array of fibers with different lengths are fused into a single output fiber. A photon-counting detector is used to record the arrival time of photons incident on the array, allowing to reconstruct which fiber the photons entered. This scheme allows us to measure the spatial light distribution of single photons.

Session 1: It’s a Science Thing
Quantifying precise measurements is critical in any field . Our research focuses on advancing quantum optical methods in the study of metrology . SPIDER is an interferometric approach to characterizing (mathematically describing) ultrashort laser pulses in the frequency domain . Our research aims to develop a sister method to the accepted SPIDER approach, dubbed Time-SPIDER . Its purpose is to use the same approach as SPIDER, but rather in the temporal domain . The procedure is to first develop the theoretical framework, and then set up the experiment . At the moment, our work approaches the issue from a purely theoretical perspective . We find that the Time-SPIDER method is useful as a direct measurement technique for non-ultrashort pulses . Many industry-standard interferometers require an iterative approach to pulse characterization, which may not be well- calibrated if the pulse is not ultrashort . Time-SPIDER solves both of these issues . If we are able to move past the theory and create a working Time-SPIDER, it would be possible to continue with other projects in the lab that may require such set-up . In the grand scheme, Time-SPIDER is a step towards continuing the study of metrology, along with quantum optics itself .
