Abstract

Large area 2D Selective Area Growth (SAG) of Multi-Quantum Well (MQW) structures is a key methodology required for realization of monolithic multicolor arrays of Photonic Crystal Surface Emitting Lasers (PCSELs) We present a study of InGaAs/GaAs MQWs selectively grown in square SAG windows with dimensions up to 300 x 300 μm², by MOCVD. The range of QW emission wavelengths and thickness enhancements are elucidated by room-temperature μ-Photoluminescence (PL) and Optical Profilometry (OP) mapping, respectively. It is shown that large areas, ⪅ 100 x 100 μm2, with uniform PL emission can be achieved within a PL tuning range of 86 nm.
