Abstract
The present invention is a semiconductor diode laser array which favors oscillation in the zero degree phase shift mode. The array comprises first and second sets of waveguides which are interdigitated in a coupling region. Energy transfer between the first and second sets of waveguides by way of evanescent coupling is needed to define the feedback paths for sustaining laser oscillations in the waveguides. Such coupling is optimum and the threshold current for lasing lowest when all of the waveguides in both sets oscillate in phase.
