Exceptional points and lasing self-termination in photonic molecules
We investigate the rich physics of photonic molecule lasers using a non-Hermitian dimer model. We show that several interesting features, predicted recently using a rigorous steady-state ab initio laser theory (SALT), can be captured by this toy model. In particular, we demonstrate the central role played by exceptional points (EPs) in both pump-selective lasing and laser self-termination pheno...
متن کاملPolarization of lasing emission in microdisk laser diodes
TE polarization of optical emission from microdisk laser diodes of radius R55 mm, thickness L50.3 mm, is found to dominate both below and above room-temperature lasing threshold current, I th 52 mA. TE emission in the lasing mode at l51560 nm wavelength is due to higher optical gain for TE modes in the quantum well device. In our device geometry, the intrinsic whispering gallery resonances have...
متن کاملLasing in chiral photonic structures
This article presents a review of the lasing and photonic properties of periodic onedimensional anisotropic structures with the symmetry of a double helix. Examples are selforganized cholesteric liquid crystals (CLCs) and sculptured thin films created by vapor deposition. A reflection band with sharp, closely spaced transmission peaks at its edges occurs for circularly polarized light with the ...
متن کاملCoupling of whispering-gallery modes in size-mismatched microdisk photonic molecules.
Mechanisms of whispering-gallery (WG)-mode coupling in microdisk photonic molecules (PMs) with slight and significant size mismatches are numerically investigated. The results reveal two different scenarios of modes interaction depending on the degree of this mismatch and offer new insight into how PM parameters can be tuned to control and modify WG-mode wavelengths and Q factors. From a practi...
متن کاملStrong coupling of different cavity modes in photonic molecules formed by two adjacent microdisk microcavities.
Strong couplings between cavity modes in photonic molecules formed by two preselected nearly identical microdisk microcavities with embedded quantum dots are investigated. By continuously tuning the refractive index of one microdisk, clear anticrossings in the resonant peak energies associated with crossings in the peak linewidths can be observed. The coupling strengths are extracted by the cou...
