Book excerpt: This program developed waveguide diode ring lasers (WDRLs) for incorporation onto laser modules for applications in data transmission requiring low noise, single mode sources which can be incorporated as arrays into small, inexpensive modules with moderate output powers. Capabilities of WDRLs developed in this program include wavelengths at 1.3 micron and shorter, 30 db side-mode-suppression ratios, tens of milliwatts of Output power, relative intensity noise of -150 dbm, threshold current down to 5 mA, direct modulation bandwidth of 9 GHz, electrically-switched beam steering, highly integrable and low-cost manufacturability based on etch-defined optical cavities and planar processing technologies which do not require regrowth, and monolithic integration of lasers, detectors and amplifiers. The key concepts enabling this performance are protected under two patents. Techniques for passive alignment of 12-laser arrays to single mode fiber ribbon were developed. Materials for monolithic lasers on Si were developed which showed stimulated emission and should enable cheap, passive alignment of large laser arrays with single mode fibers.
