Numerical simulation of vertical cavity surface emitting lasers
Optics Express, 1998 The semiconductor laser simulator MINILASE is being extended to simulate vertical cavity surface emitting lasers (VCSELs). The electronic system analysis for VCSELs is identical to that for edge emitting lasers. A brief discussion of the capabilities of MINILASE in this domain will be presented.

Multimode VCSEL model for wide frequency-range RIN simulation [PDF]
, 2008 In this paper, we present an equivalent circuit model for oxide-confined AlGaAs/GaAs VCSEL with the noise contribution adapted to optomicrowave links applications. This model is derived from the multimode rate equations.

Large mode-volume, large beta, photonic crystal laser resonator
AIP Advances, 2014 We propose an optical resonator formed from the coupling of 13, L2 defects in a triangular-lattice photonic crystal slab. Using a tight-binding formalism, we optimized the coupled-defect cavity design to obtain a resonator with predicted single-mode ...

Low-threshold surface-emitting colloidal quantum-dot circular Bragg laser array
Light: Science & ApplicationsColloidal quantum dots (CQDs) are attractive gain media due to their wavelength-tunability and low optical gain threshold. Consequently, CQD lasers, especially the surface-emitting ones, are promising candidates for display, sensing and communication ...

Thin-film photonic crystal LEDs with enhanced directionality
, 2010 The use of photonic crystals for light extraction from light-emitting diodes (LEDs) gives the possibility to shape the farfield emission pattern. This is of particular interest for étendue-limited LED applications that require a more directional ...

Vertical-Cavity Surface-Emitting Laser With a Chiral Nematic Liquid Crystal Overlay
IEEE Photonics Journal, 2014 We demonstrate measurement results of the light emission of vertical-cavity surface-emitting lasers (VCSELs) with chiral liquid crystal (CLC) overlay (CLC-VCSEL). Two different CLC materials with different chiral-phase temperature range are presented and
