New solid-state physics based approach is developed for analysis of the paraxial light propagation in two-dimensional (2D) photonic lattices of coupled dielectric waveguides or microcavities. In particular, using Maxwell's equations, a non-Hermitian Hamiltonian eigenproblem with respect to the spinor wave function of a photon is obtained for energy-dissipating photonic microstructures. The Hamiltonian is suitable for almost the entire subclass of 2D structures encompassing arrays of semiconductor microcavities and microstructured photonic crystal fibers, characterized by light propagating mostly normal to the periodic lattice plane. Methods of numerical solution are discussed and the formalism is applied to a square array of coupled semiconductor microcavities, revealing reach possibilities for tailoring photonic band structure both in the photon energy and photon lifetime energy broadening domains. In particular, a feasibility to open a double photonic crystal band gap simultaneously in the energy and lifetime energy broadening domains is demonstrated.

“…Regular coupled semiconductor laser arrays (each laser is emitting the fundamental mode) exhibit predominantly antiphase supermodes (relative phase of neighboring elements fields is π ). This tendency is unfortunate for the purpose of generating single-lobed far field, and substantial efforts were focused on attempts to coherently lock laser arrays in phase (all lasers have identical phases) [42][43][44][45][46][47][48]. Figure 1 illustrates the schematic of a vertical cavity surface emitting laser (VCSEL) array which was employed in our experiment.…”

Spontaneous locking of optical vortices in coupled semiconductor lasers

et al. 2014

Non-conventional emission of light, comprising engaged rotating light cogs, is measured and analyzed. The source of this unique emission is an array of coupled surface emitting lasers, each emitting an optical vortex. The complex rotating light structures are formed spontaneously by specific combinations of the individual vortices, each carrying two types of "charge": orbital angular momentum (±1 topological charge) and a relative engagement phase (0 or π ). These charges determine the specific form in which the individual rotating fields are engaged to generate the emanated light gear. The experimentally observed formations and dynamic evolution of the light gears stem from the complex nonlinear dynamics of the coupled rotating-field emitters, a mechanism which we have successfully modeled and utilized for interpreting the obtained results. The engaged light gears can be used in controlled generation and transmission of multiple degrees of freedom photons, for high-bit-rate classic and quantum telecommunications, particle manipulation, and super-resolution imaging.
