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： Coherent light sources combining a semiconductor optical source with a light diverging region, such as a flared resonator type laser diode or flared amplifier type MOPA, with a single lens adapted to correct the astigmatism of the light beam emitted from the source is disclosed. The lens has an acircular cylindrical or toroidal first surface and an aspheric or binary diffractive second surface. The first surface has a curvature chosen to substantially equalize the lateral and transverse divergences of the astigmatic beam. Sources with an array of light diverging regions producing an array of astigmatic beams and a single astigmatism-correcting lens array aligned with the beams are also disclosed. The single beam source can be used in systems with frequency converting nonlinear optics. The array source can be stacked with other arrays to produce very high output powers with high brightness.

摘要： A high power light source having an array, bundle or separate plurality of laser diodes coupled to a same number of multimode waveguides to collect beams of light emitted from the of laser diodes is provided. An optical combiner receives the beams of light and combines the beams of light into a single forward propagating beam of light so that substantially all optical radiation within each beam of light overlaps the optical radiation each other beam to form the single beam. A reflective element is located to receive the single forward propagating beam of light and transmits greater than 60% of the single forward propagating beam of light therethrough. The reflective element reflects between 3–40% of the single forward propagating beam back to the laser diodes as feedback to stabilize said laser diodes.

摘要： A fiber tail assembly (FTA) with a micro-lens formed in the fiber tip is used to couple the laser light out of the package and along the fiber. The FTA is soldered at two points where metallized bands are deposited on the fiber pigtail, one at a fiber mount near the diode where it can be soldered into alignment with the laser diode, and two at the snout which forms a feed through the housing and seal for the package. Typically, the FTA is metallized along its entire length within the package. In this invention the two-metallized bands are separated by a region that is unmetallized.
