Paper Abstract

Twenty element resonant optical waveguide (ROW) antiguided arrays were locked to 2.6 times above the threshold level (2.6 x Ith) by injecting light from a master oscillator in a direction normal to the diode facet and only in one element of the array. The spectra and far-field output pattern of the SL were found to be independent of the MO beam position on the SL facet, and the far-field pattern was stable with wavelength detuning (i.e. no steering) . Single frequency tuning was achieved over a < 30 A spectral range, and the beam pattern was found to be stable and diffraction-limited for nearly resonant devices. Two and four coupled ROW arrays on a bar were also injection—locked by injecting an external MO into one element of one of the arrays. Two locked arrays were wavelength tuned over a 12 A spectral range.
