摘要： Monolithic asymmetric optical waveguide grating resonators including an asymmetric resonant grating are disposed in a waveguide. A first grating strength is provided along a first grating length, and a second grating strength, higher than the first grating strength, is provided along a second grating length. In advantageous embodiments, the effective refractive index along first grating length is substantially matched to the effective refractive index along second grating length through proper design of waveguide and grating parameters. A well-matched effective index of refraction may permit the resonant grating to operate in a highly asymmetric single longitudinal mode (SLM). In further embodiments, an asymmetric monolithic DFB laser diode includes front and back grating sections having waveguide and grating parameters for highly asymmetric operation.

摘要： A gain-clamped semiconductor optical amplifier having a horizontal lasing structure in which an oscillation direction of a laser is different from an amplification direction of a signal, and a method for manufacturing the gain-clamped semiconductor optical amplifier. The gain-clamped semiconductor optical amplifier includes a gain layer for amplifying an optical signal. A Bragg lattice layer is formed on both sides of the gain layer along a longitudinal direction of the gain layer for enabling light having a corresponding wavelength to resonate in a direction vertical to the longitudinal direction of the gain layer. A passive light waveguide restrains light resonating between lattices of the Bragg lattice layer. An electrode supplies current to the gain layer, and a current-blocking layer prevents current from flowing to an area other than the gain layer.

摘要： A distributed-feedback laser has a diffractive grating, an optical waveguide layer, and an active region. The optical waveguide layer has equivalent refractive indexes larger towards cavity end facets and smaller towards a device center portion along a cavity. The active region containing the optical waveguide layer has widths wider towards the cavity end facets and narrower towards the device center portion along the cavity. The optical waveguide layer has a uniform electric intensity distribution along the cavity to improve the linearity of current versus optical output characteristics. In another arrangement, the optical waveguide layer formed on the diffractive grating has in its compositions longer wavelengths towards the cavity end facets and shorter wavelengths towards the cavity center portion along the cavity, whereby the optical waveguide layer has a uniform optical intensity distribution along the cavity to improve the linearity of current versus optical output characteristics. The distributed-feedback laser provided is with improved analog modulation distortion characteristics.
