Abstract

Semiconductor master oscillator power amplifier (MOPA) devices based on the resonant transmission properties of resonant-optical-waveguide (ROW) antiguided structures are shown to be promising candidates for stable, coherent, high-power sources. A novel mast oscillator for this type of MOPA is proposed: the three-core antiresonant reflecting optical waveguide (ARROW) diode laser. This device is also based on ROW antiguided structures and can easily be integrated with the power amplifier. Three-core ARROW lasers are shown to have large intermodal discrimination against unwanted modes, and when used as the maser oscillator of a ROW-MOPA, a uniform near-field, flat-phasefront, diffraction-limited beam output is obtained. Experimentally, 350 mW diffraction-limited beam operation has been demonstrated in ROW-MOPA devices without extremely low AR coatings.
