Abstract

In this Letter, we propose defect-mode lasing from a one-dimensional asymmetric photonic structure with dye-doped nematic liquid crystal as a central defect layer. The local field intensity of the distinguished single defect mode at the overlapped photonic band edges is drastically enhanced by the asymmetric structure consisting of two distinct multilayer photonic crystals. With high density of states of photons, effective output lasing emission and maximum input excitation are ensured. As a result, the single-mode lasing with a low excitation threshold of 0.2μJ/pulse is achieved due to the combination of the defect layer and the photonic band edge effect.

(c) Absorption (olive dotted line) and fluorescence emission (orange solid line) spectra of 0.7 wt. % dye dispersed in LC. (d) Corresponding emission spectrum of the asymmetric structure containing a defect layer of DDLC.

Simulated spectral variations of an asymmetric PC 1–DDLC–PC 2 all caused by changing the central bandgap wavelengths of the two constituent PC substrates at (660, 480), (650, 490), and (630, 530) nm from the top to the bottom. The wavelength range of the PBG overlapping increases as the central wavelengths move toward each other, resulting in a sharper defect-mode peak at the band edge intersection.
