Steady‐state analysis of a directional square lattice band‐edge photonic crystal lasers

Abstract

The original square‐lattice band‐edge structure emitted light in different directions. In a recent paper [18], we have improved the directivity of these structures by using a honeycomb photonic crystal to shield the original structure. This has improved the performance of such devices, in such a way that light can be coupled directionally to a large waveguide. In this paper, we present a steady‐state analysis of the performance of this directive device and study the amount of power which can be coupled into the waveguide, analyzing its performance as an in‐plane emitter and the limitations caused by vertical losses. © 2005 Wiley Periodicals, Inc.

Sierpinski Gasket triangular quantum dot lasers

“…photonic crystal laser) and emit very low power in the order of p W to n W [14]. In order to increase the power emitted by the laser, it would be necessary to increase its volume leading to multimode behavior.…”

“…The rate equations that describe the evolution of the characteristics of quantum dot lasers are described by equations (1)-(3) [14,18,19]. It is assumed that the devices are optically pumped in the vertical direction by a laser with a wavelength of 63 7 nm and spot size diameter of 6 f.. lm.…”

Performance assessment of hybrid surface emitting lasers with lateral one-dimensional photonic-crystal mirrors

“…However, this criterion is subjective and results based upon FDTD simulations can provide a better understanding. In order to assess the optical losses as a function of the number of periods of the PhC, we place a source with a Gaussian waveform in the active layer [13,[37][38][39]. Initially a small spot-size diameter for the source ͑ s ͒ was used to determine the electric field distribution of the eigenmode in the PhC.…”
