Here we fabricate a vertical cavity structure designed to operate as a saser oscillator device at a frequency of 325 GHz. ... SL and, at each end of it, the SL Bragg reflectors.

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have theoretically demonstrated that ...

A critical aspect of fabricating gallium nitride-based vertical-cavity surface-emitting lasers (VCSELs) is controlling the cavity length. Conventional cavity length control methods have resulted ...

Even without a direct therapeutic application, Dr. Yvonne Mowery, a radiation oncologist at Duke University, said she “was quite shocked that we are in 2020 and have a new structure identified ...
