Notes:
Single lateral 180° phase mode operation is realized at a light output of up to 90 mW under pulsed operation using uncoated AlGaAs phased array lasers. Phased array lasers consist of six elements. Each element has a self-aligned structure, with an interface layer of low AlAs mole fraction, and is fabricated by a two-step metalorganic chemical vapor deposition method, together with dry etching. Spectrally resolved, near-field measurements show that the phased array laser oscillates in a completely single lateral mode under pulsed operation. Measurements also show that a slight broadening of the far-field lobes under continuous wave operation is caused by generation of multiple lateral modes.
