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 higher-order defect mode can be designed to be confined by a photonic bandgap in such a thick slab. Using simulations, we show that a high Q of >10(5) is possible from a finely tuned second-order hexapole mode (2h). Experimentally, we achieve optically pumped pulsed lasing at 1347 nm from the 2h with a peak threshold…

Sub-microWatt threshold nanoisland lasers
A single-cell nanobeam laser with a nanoisland quantum well is proposed and demonstrated and will provide a new platform to engineer fundamental light–matter interactions by controlling the size and the location of the nanoemitters, allowing the realization of highly efficient nanophotonic devices.


Photonic crystal nanocavity laser in an optically very thick slab.
Numerical simulation reveals that when T≥800 nm, over 90% of the laser output power couples to the PhC slab modes, suggesting a new route toward an efficient in-plane laser for photonic integrated circuits.
High-Q impurity photon states bounded by a photonic band pseudogap in an optically thick photonic crystal slab
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 photonic band gap.
Electrically Driven Single-Cell Photonic Crystal Laser
The experimental demonstration of an electrically driven, single-mode, low threshold current (∼260 μA) photonic band gap laser operating at room temperature is reported, a small step toward a thresholdless laser or a single photon source.
Guided modes in photonic crystal slabs
We analyze the properties of two-dimensionally periodic dielectric structures that have a band gap for propagation in a plane and that use index guiding to confine light in the third dimension. Such

The resonant modes found in a modified single-defect two-dimensional photonic crystal slab structure are theoretically and experimentally studied. There exist several modes in the band gap: doubly
Room-temperature continuous-wave operation of lateral current injection wavelength-scale embedded active-region photonic-crystal laser.
A wavelength-scale embedded active-region photonic-crystal laser using lateral p-i-n structure that effectively reduce the thermal resistance is developed, an important step towards on-chip photonic network applications.
