Two U-M students receive scholarships from the International Society for Optics and Photonics

Hanzhang Pei (ECE) and Darwin F. Cordovilla Leon (Applied Physics) were selected for their potential contributions to the field of optics, photonics or related field.| Short Read

SPIE, the international society for optics and photonics, has awarded $298,000 in education scholarships to 84 outstanding SPIE student members based on their potential contribution to optics and photonics, or a related discipline. Award-winning applicants were evaluated, selected and approved by the SPIE Scholarship Committee.

Below are the U-M students who received scholarships.

Hanzhang Pei is a PhD candidate at the University of Michigan (USA) in Electrical and Computer Engineering and Scientific Computing. Advised by Dr. Almantas Galvanauskas, he is currently working on the coherent temporal combining of ultrashort pulses and energy extraction from fiber amplifiers, which will enable next-generation particle accelerators and many more exciting applications. Pei will also serve as the President of the Optics Society at the Univ. of Michigan Chapter this coming year.

Darwin F. Cordovilla Leon is a PhD candidate in the Applied Physics Program at the University of Michigan, Ann Arbor. He is also an NSF Graduate Research Fellow and University of Michigan Rackham Merit Fellow. Cordovilla Leon studies the dynamics of excitons in Van der Waals materials using spatially and temporally-resolved optical spectroscopy techniques under the supervision of Professors Parag B. Deotare and Duncan G. Steel. His vision is to develop energy efficient, on-chip opto-excitonic devices for applications in information processing, energy harvesting, and communications.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
