Abstract: A grating-stabilized semiconductor laser comprises a semiconductor laser gain medium, an integrated low-index waveguide, and a waveguide grating segment providing optical feedback for laser oscillation. The laser may be adapted for multi-mode or single-mode operation. A multiple-mode laser may oscillate with reduced power and/or wavelength fluctuations associated with longitudinal mode wavelength shifts, relative to Fabry-Perot lasers lacking gratings. A single-mode laser may include a compensator, wavelength reference, and detector for generating an error signal, and a feedback mechanism for controlling the compensator for maintaining the laser wavelength locked to the reference. The laser may include means for altering, enhancing, tuning, and/or stabilizing the waveguide grating reflectivity spectral profile.

Abstract: The launch conditions (injected beam size/shape, radial/angular offset from the multimode fiber axis) may be varied to preferentially excite certain transverse modes of multimode optical fiber. To reduce multimode dispersion in the fiber, modes are excited having smaller amplitudes near fiber index defects. Launch conditions may be controlled using a substrate with grooves for launching and receiving fibers, a planar waveguide formed on a substrate along with a groove for aligning the multimode fiber and waveguide, or free-space optical components. A waveguide may provide the desired injected beam size/shape. Spatially selective material processing enables accurate alignment of the groove(s) (and hence the fiber(s) therein), yielding the desired radial/angular offsets. Radial and azimuthal angular offset launch may be employed for constructing an optical mode conditioner, a transmit optical subassembly (TOSA), and other optical devices, assemblies, and subassemblies that launch an optical signal into a multimode optical fiber.
