Abstract :
A detailed study of the InGaAsP-InP 2D-lattice MQW laser has been undertaken. Characterisation of the optical field intensity as a function of distance along the device cavity has shown that etching significantly alters the optical properties of the waveguide. A high value of coupling coefficient is obtained, with Kg >250cm -1. Modelling suggests that this high value is consistent with the mode-hop free single-mode emission found to hold in the etched device even under large-signal modulation at 10 Gb/s
