Cavity parameter deviations from their nominal values affect phase-locking in vertical-cavity surface-emitting lasers (VCSEL) arrays. The phase-locking tolerance is studied analytically and numerically for both random as well as systematic parameter

Gain-guided eigenmodes in open VCSEL cavities are constructed by superposition of paraxial (i.e., Gauss-Laguerre) (GL) modes, employing the effective cavity hard mirror equivalent for the DBRs. A generic round-trip matrix is obtained analytically for

We compare the results of different optical vertical-cavity surface-emitting laser models on the position-dependent effects of thin oxide apertures. Both scalar and vectorial models as well as hybrid models are considered. Physical quantities that ar

When the RF amplitude in a crossed field device is much smaller than the external DC voltage, the energy exchange between an electron and the wave is given by the change in the potential energy of the electron guiding center. The shift of the beam ce

A closed, nonlinear set of fluid equations, based on the electron guiding center orbits, is developed to model the CFA behavior. In synchronism with the RF signal frame, the streamlines follow the equipotential surfaces of the transformed fields. In

A guiding center fluid model involving a single RF mode of slowly varying amplitude and phase is used to study the long-time behavior of a distributed emission, reentrant crossed-field amplifier. The space charge recirculation through the drift space

Summary form only given. Microcavities with small features, such as oxide apertures and etched mesa edges, suffer wide angle scattering that cannot be treated by paraxial propagation or by lens-like phase shifts. We present a systematic treatment usi

Cavity interactions due to lateral fringe field overlap or "stray" reflections from optical elements in a vertical-cavity surface-emitting laser (VCSEL) array based interconnects are studied. Interacting cavity pairs act as coupled oscillators. Depen
