Abstract

In this paper, we are investigating the growth of a ZnSe based vertical cavity surface emitting laser (VCSEL). Undoped and p-type doped distributed Bragg reflectors (DBRs) with reflectivities exceeding 99% have been grown by molecular beam epitaxy (MBE) using Zn(S)Se layers for the high refractive index material and ZnSe/MgS superlattices (SLs) for the low index material. An undoped monolithic VCSEL structure containing a ZnCdSSe quantum well (QW) emitting in the blue-green reaches a quality factor (Q-factor) of 100, which is the best value reported so far. Temperature dependent photoluminescence (PL) measurements show that the emission of the QW is effectively guided by the cavity resonance.
