Lorenz-Mie theory for 2D scattering and resonance calculations
Denis Gagnon, Louis J. Dubé
This PhD tutorial is concerned with a description of the two-dimensional generalized Lorenz-Mie theory (2D-GLMT), a well-established numerical method used to compute the interactio…
Toward the formation of crossed laser-induced periodic surface structures
Jean-Luc Déziel, Joey Dumont, Denis Gagnon +3
The formation of a new type of laser-induced periodic surface structures using a femtosecond pulsed laser is studied on the basis of the Sipe-Drude theory solved with a FDTD scheme…
Optimization of integrated polarization filters
Denis Gagnon, Joey Dumont, Jean-Luc Déziel +1
This study reports on the design of small footprint, integrated polarization filters based on engineered photonic lattices. Using a rods-in-air lattice as a basis for a TE filter a…
Adding SALT to Coupled Microcavities: the making of active photonic molecule lasers
Denis Gagnon, Joey Dumont, Jean-Luc Déziel +1
A large body of work has accumulated over the years in the study of the optical properties of single and coupled microcavities for a variety of applications, ranging from filters t…
Ab initio investigation of lasing thresholds in photonic molecules
Denis Gagnon, Joey Dumont, Jean-Luc Déziel +1
We investigate lasing thresholds in a representative photonic molecule composed of two coupled active cylinders of slightly different radii. Specifically, we use the recently formu…
Multiobjective optimization in integrated photonics design
Denis Gagnon, Joey Dumont, Louis J. Dubé
We propose the use of the parallel tabu search algorithm (PTS) to solve combinatorial inverse design problems in integrated photonics. To assess the potential of this algorithm, we…
S and Q Matrices Reloaded: applications to open, inhomogeneous, and complex cavities
Guillaume Painchaud-April, Joey Dumont, Denis Gagnon +1
We present a versatile numerical algorithm for computing resonances of open dielectric cavities. The emphasis is on the generality of the system's configuration, i.e. the geometry…
Coherent beam shaping using two-dimensional photonic crystals
Denis Gagnon, Joey Dumont, Louis J. Dubé
Optical devices based on photonic crystals such as waveguides, lenses and beam-shapers, have received considerable theoretical and experimental attention in recent years. The produ…
Beam shaping using genetically optimized two-dimensional photonic crystals
Denis Gagnon, Joey Dumont, Louis J. Dubé
We propose the use of two-dimensional photonic crystals with engineered defects for the generation of an arbitrary-profile beam from a focused input beam. The cylindrical harmonics…
Phase Space Engineering in Optical Microcavities II: Controlling the far-field
Julien Poirier, Guillaume Painchaud-April, Denis Gagnon +1
Optical microcavities support Whispering Gallery Modes (WGMs) with a very high quality factor Q. However, WGMs typically display a far-field isotropic emission profile and modifyin…
Phase Space Engineering in Optical Microcavities I: Preserving near-field uniformity while inducing far-field directionality
Guillaume Painchaud-April, Julien Poirier, Denis Gagnon +1
Optical microcavities have received much attention over the last decade from different research fields ranging from fundamental issues of cavity QED to specific applications such a…
