"An optical emitter assembly is described in which one or more optical devices each having an emitting aperture at a surface thereof can be mounted on a carrier such that the plane(面)of the emitting apertures with respect to a well defined reference plane(基準面)can be precisely controlled. This enables additional optical elements to be precisely axially and laterally positioned with respect to the centre of the emitting apertures, even when there are plural optical devices of differing thicknesses. The assembly may comprise a surface-emitting optical device having an emission surface(発光面)providing an optical output aperture; a carrier having first and second opposing surfaces, the first surface being a reference surface(基準面)on which the optical device is mounted by its emission surface and the second surface being a back surface(背面、裏面), the carrier having an aperture extending between the reference and back surfaces, the optical device being positioned on the reference surface such that its optical output aperture is in overlying relation with the carrier aperture to direct optical radiation therethrough.”

"7. The assembly of claim 4 in which the tapered cavity is etched preferentially along crystallographic planes(結晶面)of the carrier material."

"Each of the crystallographic planes(結晶面)in sapphire discussed herein are as is commonly known in the art. It is to be understood that as used herein, mention of a particular orientation of a crystal sheet to a specific plane include all off-angle or mis-angle, miscut, or the like(その他の、等の;*形容詞)orientations in which the reference plane(基準面)is tilted to another plane. For example, it is often desirable to product crystal sheets having a general A-plane or C-plane orientation, but include a desired tilt or miscut angle toward the M-plane. Accordingly, use of the phrase "A-plane" or "C-plane" for example, include this plane as the general reference plane with any desired offcut or misangle orientation."

"Increased yield of optical elements from cubic crystal rods, such as made of calcium fluoride, is made possible by orienting the optical elements for supporting the propagation of light along one of the , , or < 2 1 1> alternative crystal axis, which extend perpendicular to(垂直)a main crystal axis. A cleave is taken(劈開される)through the crystal rod along a primary crystal plane(主結晶面){1 1 1} normal to(垂直)the main axis. One of the , , or < 2 1 1> alternative crystal axes is located by optical inspection and indicated on the crystal rod with an orientation label. Additional cuts are taken(切断が行われる)parallel to the {1 1 1} primary crystal plane to divide the crystal rod into disks each containing a portion of the orientation label. The disks can be cut again and sides formed perpendicular to the {1 1 1} primary crystal plane with regard to the orientation labels for forming optical elements, such as prisms, oriented for supporting the propagation of polarized light along one of the , , and < 2 1 1> alternative crystal axes."

"[0018] In Step B, the crystal rod 10 is cleaved near one end along the {1 1 1 } plane normal to(垂直)the main axis, in such calcium fluoride crystals, this is the crystal plane along which the crystal most readily breaks and provides a convenient and accurate reference plane(基準面)14 for the crystal rod 10. Although the {1 1 1 } reference plane 14 identifies one of the crystal axes, i.e., the main crystal axis, it is necessary to identify a second axis to fully orient the cubic crystal.

[0019] Step C involves an inspection procedure for identifying a second crystal axis orthogonal to(垂直)the main axis, in particular, a Laue x-ray diffractometer is used to find one of the , , or < 2 1 1> alternative crystal axes. Two orientation labels 16 and 18 are applied to the periphery of the crystal rod 10 to identify the location of one of the , , or < 2 1 1> alternative crystal axes that extends perpendicular to the main axis. The orientation labels 16 and 18 are preferably drawn on the crystal rod 10 as two diametrically opposed lines.

[0020] Using the {1 1 1 } reference plane 14 as a reference, parallel cuts 20 are made(切断が行われる)along the length of the rod 10 as shown in Step D, each at a predetermined thickness "T". The parallel cuts 20 divide the crystal rod 10 into a plurality of slabs in the form of slightly eccentric disks 22 as shown in Step E. For example, the crystal rod 10 can be mounted in(上に取り付け)a sacrificial plastic holder and loaded into a saw, such as a ID or diamond saw, and accurately cut onto the plurality of eccentric disks 22. The tops and bottoms of the eccentric disks 22 are then double-side lapped to create highly parallel ground surfaces 24 and 26 in much the same way as(ほぼ同じ方法で)optical windows are formed. The top and bottom surfaces 24 and 26 of the disks 22 are ground parallel to the {1 1 1} reference plane 14 coincident with other of the set of parallel {1 1 1 } planes. The main axis extends normal to(垂直)the cut parallel surfaces 24 and 26 of the disks 22. The , , and < 2 1 1> alternative crystal axes are known to be oriented perpendicular to the main axis and parallel to the {1 1 1 } planes that form the parallel surfaces 24 and 26 of the disks 22. The orientation labels 16 and 18, which are visible on each of the disks 22, identify the orientation of the one , , or < 2 1 1> alternative crystal axis around the main axis in each of the disks 22."

"FIG. 15B is an enlarged, isometric illustration of the wing tip(翼先端部)1520 and the vortex dissipation device 1530 shown in FIG. 15A. The wing tip 1520 can include a tip surface(先端面)1521 that can be flat in some embodiments, hemicylindrical in other embodiments, and curved in multiple dimensions and about multiple axes in still further embodiments. In any of these embodiments, the vortex dissipation device 1530 can include one or more nozzles 1590 (fourteen are shown in FIG. 15B for purposes of illustration), each having a nozzle orifice 1591. In a particular aspect of this embodiment, the nozzle orifices 1591 are positioned to be generally flush with(同一平面、面一、ツライチ)the tip surface 1521. In other embodiments, the nozzle orifices 1591 can have other arrangements (e.g., slightly recessed from the tip surface 1521). The nozzle orifices 1591 can be located behind a movable door when the nozzles 1590 are not in use, in a manner generally similar to that described above with reference to FIG. 5A. For purposes of illustration(説明のため), such a cover is not shown in FIG. 15B. The nozzle orifices 1591 can be arranged in particular patterns, for example multiple rows 1594 (shown in FIG. 15B as a first, e.g., upper, row 1594a and a second, e.g., lower, row 1594b). The flow of air or another gas directed through the nozzles 1590 can be controlled and varied in a time-dependent manner to hasten the dissipation of vortices emanating from the wing tip 1520, as described further below with reference to FIGS. 16A-22."
