Adjoint-optimized nanoscale light extractor for nitrogen-vacancy centers in diamond
Nanophotonics, 2020 We designed a nanoscale light extractor (NLE) for the efficient outcoupling and beaming of broadband light emitted by shallow, negatively charged nitrogen-vacancy (NV) centers in bulk diamond.

Afterglow Light Curve Modulated by a Highly Magnetized Millisecond Pulsar [PDF]
, 2001 We investigate consequences of a continuously energy-injecting central engine of gamma-ray burst (GRB) afterglow emission, assuming that a highly magnetized pulsar is left beaming in the core of a GRB progenitor.
