Analogs of spontaneous emission and lasing in photonic time crystals
Kyungmin Lee, Minwook Kyung, Yung Kim +7
We report the first direct mapping of the frequency-resolved local density of states (LDOS) in a photonic time crystal (PTC) implemented as an array of time-periodically modulated…

Spontaneous emission decay and excitation in photonic time crystals
Jagang Park, Kyungmin Lee, Ruo-Yang Zhang +10
Over the last few decades, the predominant strategies for controlling spontaneous emission have involved tailoring the spatial surroundings of quantum emitters or atoms to create r…
