Abstract

The effects of inter-ridge coupling on both the static and high frequency properties of twin stripe laterally coupled lasers emitting at a wavelength of 1.3 micrometers are investigated. It is found that when both ridges are lasing, the emission spectrum is multi longitudinal mode, with each peak being single valued close to threshold, or split in two at higher biases. Spectrally resolved near and far field measurements are made which clearly distinguish that the system lases predominantly in the out-of-phase mode close to threshold, whereas it lases in both in-phase and out-of-phase modes at higher biases. The out-of-phase mode is found to emit at higher frequencies than the in-phase mode.
