چکیده
Photonic-crystal surface-emitting lasers (PC-SELs), with and without regrowth, are theoretically simplified as air-hole air-pillar structures, respectively. In this paper, square-latticed PC-SELs simulated by a three-dimensional coupled-wave theory model the design guideline is illustrated PC basis of right isosceles triangular double circular shapes. The optimum filling factor determined infinite cavity analysis slope efficiency finite-size PC-SEL then calculated for lowest threshold band-edge mode. comparison PC-SEL, exhibits lower gain, larger gain discrimination but efficiency. To achieve comparable value, area about four times than that PC-SEL.

Two-Dimensional Photonic Crystal Confined Vertical-Cavity Surface-Emitting Lasers
The two-dimensional photonic crystal (2-D PhC) structure has been investigated as a method for lateral mode control of vertical-cavity surface-emitting lasers (VCSELs). The 2-D PhC structures were designed using an equivalent index model developed for photonic crystal fibers combined with a plane wave expansion method. The etching depth dependence of the PhC structure was incorporated for the f...

Photonic crystal surface emitting lasers (PCSELs) [1] offer the ultimate in control in semiconductor lasers. PCSELs have been shown to have high power scaling with area, high single-mode powers [2], large scale coherent emission, control of the beam shape and polarization with design of the photonic crystal geometry [3,4], as well as beam steering [5]. The photonic crystal, a two-dimensional va...
متن کاملMid-Infrared Surface-Emitting Two Dimensional Photonic Crystal Semiconductor Lasers
The mid-infrared (mid-IR) region, covering the electromagnetic spectrum from about 2.5 to 25 ┤m wavelength, is of unique interest for many applications, especially for molecular spectroscopy, because the vibrational frequencies of almost all target molecules and hydrocarbons are in this spectral region, such as NO, NO2, CO, CO2, HF, and CH4. The specific application areas for molecular spectros...
متن کاملElectrically pumped edge-emitting photonic crystal lasers with angled facets.
We demonstrate electrically pumped large-area edge-emitting InGaAsP/InP two-dimensional photonic crystal lasers with angled facets at room temperature. The laser uses a weak index perturbation surface photonic crystal structure to control optical modes in the wafer plane. Measurements of the laser spectra show that the modal selection is due to satisfying the Bragg resonance conditions in both ...
