Higher-order defect mode laser in an optically thick photonic crystal slab
Se-Heon Kim, Jingqing Huang, Axel Scherer
The use of an optically thick slab may provide versatile solutions for the realization of a current injection type laser using photonic crystals. Here, we show that a transversely…
High-Q impurity photon states bounded by a photonic-band-pseudogap in an optically-thick photonic-crystal slab
Se-Heon Kim, Andrew Homyk, Sameer Walavalkar +1
We show that, taking a two-dimensional photonic-crystal slab system as an example, surprisingly high quality factors (Q) over 10^5 are achievable, even in the absence of a rigorous…
A photonic crystal nanocavity laser in an optically very thick slab
Se-Heon Kim, Jingqing Huang, Axel Scherer
A photonic crystal (PhC) nanocavity formed in an optically very thick slab can support reasonably high-Q modes for lasing. Experimentally, we demonstrate room-temperature pulsed la…
From vertical-cavities to hybrid metal/photonic-crystal nanocavities: Towards high-efficiency nanolasers
Se-Heon Kim, Jingqing Huang, Axel Scherer
We provide a numerical study showing that a bottom reflector is indispensable to achieve unidirectional emission from a photonic-crystal (PhC) nanolaser. First, we study a PhC slab…
Vertical beaming of wavelength-scale photonic crystal resonators
Se-Heon Kim, Sun-Kyung Kim, Yong-Hee Lee
We report that of the photons generated inside a photonic crystal slab resonator can be funneled within a small divergence angle of . The far-field radiation…
Two-dimensional heterogeneous photonic bandedge laser
Soon-Hong Kwon, Se-Heon Kim, Sun-Kyung Kim +2
We proposed and realized a two-dimensional (2D) photonic bandedge laser surrounded by the photonic bandgap. The heterogeneous photonic crystal structure consists of two triangular…
