Abstract: A photonic local oscillator system for the Millimeter Array is described. The mixing of coherent infrared signals generated at a central location and distributed in the 1.3 - 1.55 micrometer wavelength window over optical fiber holds the promise of savings in both cost and manpower over a conventional system. This proposed system, using the many commercially developed components now available also offers advantages in ease of maintenance and reliability. !8
