摘要： To achieve stable multimode output even when driven by a drive current near a threshold value, provided is a laser apparatus comprising a semiconductor laser element; a wavelength selecting element that performs laser oscillation by forming a resonator between itself and a reflective surface of the semiconductor laser element to output oscillated laser light; and an optical system that is optically coupled to an emission surface of the semiconductor laser element with a coupling efficiency η and inputs to the wavelength selecting element light output from the emission surface. The optical system causes a value that is correlated with a minimum light output within a linear light output region in which light output is linear with respect to an injection current injected to the semiconductor laser element to be less than this value occurring when the coupling efficiency η is at a maximum.

摘要： A laser package comprises a laser diode source having a first Fabry-Perot cavity between a highly reflective back facet and low reflective front facet for providing a first light output for an optical application. A light monitor is positioned adjacent to the back facet and aligned to receive a second light output from the laser diode back facet. A pigtail fiber having a lensed fiber input end is positioned from the laser diode front facet to form an optical coupling region and is aligned relative to the lasing cavity to receive the first light output into the fiber, the light output exiting the package for coupling to the application. A portion of the first light output from the lasing cavity is reflected off the lensed fiber input end with a portion directed back into the lasing cavity and another portion reflected off of the laser diode front facet. The front facet forms with the lensed fiber input end a second Fabry-Perot cavity generating light which is periodically in and out of phase with the light generated in the first Fabry-Perot cavity due to changes in the length of the second Fabry-Perot cavity caused by package ambient temperature changes so that a tracking error is generated in a signal developed by the light monitor. Thus, this invention provides several ways to suppress the formation of the second Fabry-Perot cavity.

摘要： A microlens on the end of an optical fiber has reduced back reflections to a light source, such as a pump laser diode. In a particular embodiment, the microlens is lapped on two radii, at least one of which is offset from the center axis of the fiber, to form a point on the end of the fiber, thus reducing a surface for reflecting light back to the light source. In another embodiment, the microlens is formed with two different side surface angles to accommodate misalignment of the light source to the fiber mount. In another embodiment a Fresnel lens structure on the end of the fiber operates optically as an angled chisel lens.

摘要： An optoelectronic laser module, in particular for dense wavelength division multiplex systems, is described. The laser module has a laser diode with an active region, an optical resonator containing a highly silvered reflecting surface and a Bragg interference grating which provides frequency-selective feedback, and a housing which accommodates the laser diode and has a holder for coupling an optical conductor. The Bragg interference grating is configured as a fiber Bragg grating in an optical conductor and the optical conductor is connected to the housing via the holder. As a result, it is possible with the use of standard components to provide a laser having an external resonator whose emission wavelength can be set in a simple way by suitable selection of the fiber Bragg grating.
