“…Refinements in design [8] and fabrication [9] have further improved the performance of these devices, resulting in predicted Q values of up to 3 × 10 4 (the highest predicted Q for the designs in [10] was 2 × 10 4 ) and measured Q values of up to 2800. At the same time, other types of defect modes have been studied, including a monopole mode in the hexagonal lattice [11,12] and different types of defect modes in the square lattice [13]. The predicted Q values in these structures were also on the order of 10 4 , with a measured Q for the monopole mode of 1, 900.…”

Abstract:Building upon the results of recent work [1], we use momentum space design rules to investigate high quality factor (Q) optical cavities in standard and compressed hexagonal lattice photonic crystal (PC) slab waveguides. Beginning with the standard hexagonal lattice, the results of a symmetry analysis are used to determine a cavity geometry that produces a mode whose symmetry immediately leads to a reduction in vertical radiation loss from the PC slab. The Q is improved further by a tailoring of the defect geometry in Fourier space so as to limit coupling between the dominant Fourier components of the defect mode and those momentum components that radiate. Numerical investigations using the finite-difference time-domain (FDTD) method show significant improvement using these methods, with total Q values exceeding 10 5 . We also consider defect cavities in a compressed hexagonal lattice, where the lattice compression is used to modify the in-plane bandstructure of the PC lattice, creating new (frequency) degeneracies and modifying the dominant Fourier components found in the defect modes. High Q cavities in this new lattice geometry are designed using the momentum space design techniques outlined above.

“…Photonic crystals, 1 and planar photonic crystals in particular ͑PPC͒, 2 are promising manufacturable geometries for the realization of compact optical nanocavities and their integration with waveguides, modulators, and detectors. So far, there have been several reports on room-temperature lasing in PPC nanocavities, [3][4][5][6][7] and more recently, new high-Q cavity designs based on modification of two-dimensional ͑2D͒ photonic crystals have been proposed. 4,8 In this letter, we report the experimental application of one of these designs.…”

We have fabricated photonic crystal nanocavity lasers, based on a high-quality factor design that incorporates fractional edge dislocations. Lasers with InGaAsP quantum well active material emitting at 1550 nm were optically pumped with 10 ns pulses, and lased at threshold pumping powers below 220 W, the lowest reported for quantum-well based photonic crystal lasers, to our knowledge. Polarization characteristics and lithographic tuning properties were found to be in excellent agreement with theoretical predictions.

“…After that, this type of semiconductor lasers has been developed rapidly in near IR region. (Park, Hwang, Huh, Ryu, & Lee, 2001;Loncar, Yoshie, Scherer, Gogna, & Qiu, 2002;Altug, Englund, & Vuckovic, 2006) Unfortunately, mainly restricted by the etch-induced surface recombination, the research development of 2D photonic crystal semiconductor lasers in mid-IR range of electromagnetic spectrum was relatively slow. Even so, due to their intrinsic advantages addressed previously, this type of lasers operating in mid-IR range is still very desirable.…”
