“…published so far. The simple scalar models used in [5,6,[10][11][12] have not revealed the results presented hereby since they cannot calculate properly the PhC hole scattering losses. Furthermore, the present paper shows cw simulation of the PhC-VCSEL characteristics while our prior works [13][14][15] considered pulse operation only.…”

“…This motivates the study of the impact of the hole depth on the modal behaviour of PhC VCSELs to define the smallest aspect ratio assuring good performance. Such preliminary studies have been recently reported by the group of Choquette [5,6,10] and by Ivanov et al [11,12]. The analysis presented in [5,6,10] is based on the 2D plane-wave expansion method with an effective refractive index related to the finite depth of the holes.…”

“…In [11], the modal behavior of PhC VCSEL has been considered on the basis of the scalar, effective index method and limited to the emission wavelength only. In [12] the detailed comparison of PhC VCSEL and oxide-confined VCSEL has been performed taking into account the thermal effects as well. In our past works we performed, for the first time, the full three dimensional analysis of a cold-cavity PhC VCSEL considering the optimal direction of light emission [13], optimal parameters assuring high modal gain [14] and single mode operation in a pulse regime [15].…”

A self‐consistent electrical‐thermal‐optical‐gain modeling of threshold characteristics of an InP‐based 1300 nm AlInGaAs photonic‐crystal vertical‐cavity surface‐emitting diode laser is presented. It is shown that low threshold characteristics and strong transverse‐mode discrimination can be simultaneously achieved for optimized photonic crystal structure and current aperture.

In this work we present a spatial and dynamical model of a semiconductor vertical-cavity surface-emitting laser (VCSEL) incorporating a spatial built-in optical waveguide created by the defect in a two-dimensional photonic crystal (PC). The PC is created by an array of air-holes etched in to the VCSEL. Results of investigations of power versus current and dynamical characteristics of a conventional proton-implanted VCSEL and VCSELs incorporating PC defect waveguides operating with effective index and photonic band-gap guidances are presented and discussed. Results show that the VCSELs with incorporated PCs between laser mirrors provide a dramatic decrease of the power of the fundamental laser mode. Application of multiple-defect photonic bandgap (PBG) waveguides provides an additional dominance of the fundamental mode, and thus, the PC creates high-power but single-mode radiation of VCSELs which is impossible in conventional VCSELs.

Results of the self-consistent comprehensive analysis of a room-temperature operation of InP-based 1300-nm AlInGaAs photonic-crystal (PhC) VCSELs are presented. In particular, an influence of PhC parameters on thermal effects within VCSEL volume and its emission wavelength are analysed. The PhC has been found to introduce a number of opposite effects including a possible light leakage through PhC holes. From one side, PhC holes make more difficult heat-flux extraction from VCSEL volume leading to higher temperature increases within it. But, from the other side, a properly manufactured PhC creates an efficient radial confinement mechanism for VCSEL radiation field. It enhances an interaction between the field and the active-region carriers leading to a decrease in both the VCSEL lasing threshold and temperature increases. Seemingly both effects may similarly affect VCSEL operation, but our analysis revealed, that thermal properties of the PhC VCSEL are mainly dependent on an efficient confinement of its radiation field within the active region impeding a mode leakage through PhC holes, whereas an importance of deterioration of heat-flux extraction from VCSEL volume is much less essential. The wavelength shift induced by a change of PhC parameters has been found not to exceed 4×10−3 µm.
