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…
Comment on "Amplified emission and lasing in photonic time crystals"
Jagang Park, Hee Chul Park, Kyungmin Lee +5
Lyubarov et al. (Research Articles, 22 July 2022, p. 425) claim that the spontaneous emission rate of an atom vanishes at the momentum gap edges of photonic Floquet media. We show…
Resonance-enhanced spectral funneling in Fabry-Perot resonators with a temporal boundary mirror
Kanghee Lee, Junho Park, Seojoo Lee +4
A temporal boundary refers to a specific time at which the properties of an optical medium are abruptly changed. When light interacts with the temporal boundary, its spectral conte…
