摘要： The invention provides a fiber pigtail assembly wherein a polarization maintaining fiber is soldered directly to a mounting pad without a sleeve or a ferrule therebetween. A portion of the polarization maintaining fiber near a fiber end is embedded in a vertical slow axis orientation within an asymmetrical solder ball having a flat portion for adhering to the mounting pad. The vertical slow axis orientation of the polarization maintaining fiber within the solder ball enhances power stability and polarization extinction ratio properties of optical modules utilizing the invention.

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.

摘要： The invention relates to sources of optical radiation wherein polarized radiation from first and second rows of light emitters is first collimated and combined into two combined beam using first and second rows of collimating and beam re-directing elements, respectively, and then polarization multiplexed to form a polarization-multiplexed output beam. In order to reduce the footprint, emitters of the first and second emitter rows are disposed in an interleaved, staggered arrangement, and the second row of collimating and beam re-directing elements is disposed in a space between the first emitter row and the first row of collimating and beam re-directing elements.

摘要： A fiber coupled semiconductor device having an improved optical stability with respect to temperature variation is disclosed. The stability improvement is achieved by placing the platform holding the semiconductor chip and the optical fiber onto a spacer mounted on a base. The spacer has an area smaller than the area of the platform, for mechanical decoupling of thermally induced deformation of the base from a deformation of the platform of the semiconductor device. Attaching the optical fiber to a vertical mounting surface of a fiber mount, and additionally attaching the fiber mount to a submount of the semiconductor chip further improves thermal stability of the packaged device.
