    摘要： In a laser package, a tilted laser causes laser light to be coupled into an optical fiber at an angle relative to a fiber axis of the optical fiber. The tilted laser emits laser light at an angle relative to a lens axis of a lens such that the lens directs and focuses the laser light at the angle relative to the fiber axis. Tilting the laser allows the laser light to be coupled into the optical fiber substantially parallel to or aligned with the core of the fiber while causing back reflection to be directed away from the laser, thereby improving coupling efficiency and minimizing feedback. The tilted laser may be coupled to an angle polished fiber, for example, in a laser package such as a TO can type laser package, a butterfly type laser package, or a TOSA type laser package.

    摘要： A method for fabricating a laser for generating single-longitudinal mode laser light at a lasing wavelength. A semiconductor active region for amplifying, by stimulated emission, light in the laser cavity at the lasing wavelength is formed. A grating is formed adjacent to the active region, the grating having a grating period corresponding to a Bragg wavelength substantially equal to the lasing wavelength. An intermediate section of the grating is removed to result in first and second pluralities of gratings separated by a gratingless intermediate section. First and second grating sections are formed comprising the first and second pluralities of gratings, where the first and second grating sections each have a first effective index of refraction. A gratingless phase-shift section is formed in said intermediate section, the phase-shift section being disposed adjacent to the active region and between the first and second grating sections and having a second index of refraction different than the first index of refraction. The phase-shift section has a length sufficient to impart a phase shift for light at the lasing wavelength sufficient to achieve single-longitudinal mode operation. Alternatively, a grating material layer is deposited adjacent to the active region, the grating material layer having a first section, a second section, and an intermediate section between the first and second sections. Gratings are formed in the first and second sections to form a first grating section in the first section, a second grating section in the second section, leaving a gratingless phase-shift section in the intermediate section.

    摘要： A surface-emitting laser, such as a VCSEL, for generating single-transverse mode laser light at a lasing wavelength, has a first mirror and a second mirror positioned so as to define a laser cavity therebetween, and a semiconductor active region disposed between the first and second mirrors for amplifying, by stimulated emission, light in the laser cavity at the lasing wavelength. An annular antiguide structure is disposed within the laser cavity and between the active region and one of the first and second mirrors, the annular antiguide structure comprising an antiguide material and having a central opening, the central opening comprising a second material having an index of refraction for light at the lasing wavelength smaller than that of the antiguide material, whereby the annular antiguide structure causes preferential antiguiding of higher order transverse lasing modes in the laser cavity.

    摘要： An extended cavity Fabry-Perot laser assembly provides relatively narrow mode spacing while allowing relatively high speed optical modulation. The extended cavity Fabry-Perot laser assembly generally includes an exit reflector physically separated from a laser emitter (e.g., a gain chip) to extend the lasing cavity and narrow the mode spacing while maintaining a relatively small gain region in the laser emitter capable of higher speed optical modulation. The extended cavity Fabry-Perot laser assembly may be used in a multi-channel transmitter in a wavelength division multiplexed (WDM) optical system that selects a channel wavelength for the transmitter from among multiple channel wavelengths emitted by the laser assembly. The narrow mode spacing may be less than a WDM channel width, and more specifically, may be less than a channel passband of an arrayed waveguide grating (AWG) or other filter used to select the channel wavelength.
